Question

6. Give the names of the functional group. - (1) CHO (11) -C=O (111) -OH (iv) COOH
7. Catenation is the ability of an atom to form bonds with other atoms of the same element. It is exhibited by
both carbon and silicon. Compare the ability of catenation of the two elements. Give reasons.
8. Write the formula and electron dot structure of Carbon tetrachloride.
9. In the electron dot structure, the valence shell electrons are represented by crosses or dots.
a) The atomic number of chlorine is 17. Write its electronic configuration.
b) Draw the electron dot structure of chlorine molecule.
10. What is the general mathematical formula of alkyne?​

Answer 1

Answer:

Hope you will mark me as brainliest

Explanation:

6. CHO means Community Health Offer , COOH MEANS Carboxylic acid

7.Catenation is the ability of an atom to form bonds with other atoms of the same element. It is exhibited by both carbon and silicon. This is true because they have 4 valence electrons in their valence shell. They cannot lose 4 electrons because it would require lot of energy.

8. Carbon tetrachloride - CCI4

9.Electronic configuration of Cl = 2,8,7

So, the valence electron is 7

So, the dot structure is

       ..

  :    Cl   :

        .

10.The alkynes comprise a series of carbon‐ and hydrogen‐based compounds that contain at least one triple bond. This group of compounds is a homologous series with the general molecular formula of C n H 2 n‐‐2 , where n equals any integer greater than one.
