What will you learn in NCERT Class 11 Chemistry Chapter 11 The p-Block Elements?
The current chapter talks about p-block elements. P-block elements range from Group 13 to Group 18 in the periodic table and belong to the Boron family. The chapter emphasizes the atomic structure of the elements and their physical properties. It also talks about electronegativity and how it decreases from Boron to Aluminum and increases from thereon.
Group 13 – Boron
Boron is a strong element belonging to Group 13. It has a high melting temperature, owing to its crystalline lattice structure. However, it is not a metal. Others from the Boron family are soft metals with low melting points and high electrical conductivity.
When Boron mixes with other elements such as hydrochloric acid and water, you get different compounds like Borax and Orthoboric acid. While Borax has a white crystalline-like structure, orthoboric acid is a liquified solution of Borax. Borax is soft and soapy and finds uses in making borosilicate glazes that can resist heat. The compound also has applications in pottery for making enamels and glazes.
Similarly, when the element mixes with hydrogen compounds, it forms diborane. Diborane is a colorless gas with high toxicity.
It catches fire instantly when you expose it to the surrounding air. So, it is highly flammable.
Group 14 – Carbon
Group 14 in the periodic table consists of elements like Carbon, Silicon, Germanium, Tin, and Lead.
Carbon is an abundant element that exists in different forms, including coal, diamond, and graphite.
All the elements that form Group 14 are solids, and carbon is no exception to this rule. It has a small atomic size and high electronegativity.
Carbon exists in two forms, namely, amorphous and crystalline. Diamond and graphite are crystalline forms of carbon and find various uses, such as for the sharpening of tools used in the manufacture of dyes. It also finds applications in making tungsten filaments.
Graphite is a soft and slippery element that finds uses in lubricating machines that run at high temperatures.
Other forms of carbon include wood charcoal and animal charcoal.
Carbon has hundreds of other uses. For instance, activated charcoal can absorb poisonous gases. So, it finds applications in gas masks. It also finds uses in the decolorization of sugar.
Likewise, using carbon, you can produce black ink. Carbon also finds applications in the manufacture of automobile tyres.
Coke, a form of carbon, finds uses in metallurgical processes as a reducing agent.
Carbon can form hundreds of different compounds when mixed with other substances.
For instance, when mixed with Oxygen, Carbon forms two prominent compounds that you can find in everyday life, namely, carbon monoxide and carbon dioxide. Both these compounds differ drastically in terms of properties. While carbon monoxide is highly poisonous, carbon dioxide is less toxic. Similarly, carbon monoxide is highly porous and insoluble in water, while carbon dioxide is slightly soluble in water and forms carbonic acid when it dissolves.
Benefits of NCERT Solutions for Class 11 Chemistry Chapter 11 The p-Block Elements
There are hundreds of benefits of studying Chemistry from NCERT solutions, which is why those who aspire to come out on top prefer them. Listed below are a few benefits of preparing for class 11 exams using NCERT solutions.
1. Prepared by Experts
Teachers with extensive knowledge prepare NCERT solutions. They have only one goal in mind – To provide students of class 11 with quality educational content. So, NCERT solutions for Chemistry are concise as well as detailed and offer students with enough information to crack the exams.
2. NCERT Solutions Enable Students to Test their Knowledge
NCERT Solutions for Chemistry come with questions at the end of each chapter. So, it allows students to evaluate their knowledge of the different concepts that appear in the chapter.
3. NCERT Solutions Function as Revision Materials
NCERT solutions also help students to revise each concept in the subject before the exams begin. So, by going over the solutions, you can ensure that you answer all the questions that appear in the exams.
So, teachers should recommend to students to go through NCERT solutions for Chemistry so that they are thorough with all the concepts. The solutions are also a means by which you can answer questions that appear at the end of each chapter and assess your knowledge. Additionally, they also serve as reference materials and help clear any doubts that a student may have. So, instead of going to their teachers, students can refer to NCERT solutions and get all their doubts cleared.
