Explanation / Answer

4)

Number of valence electrons in C = 4

Number of valence electrons in H = 1

So,

total number of valence electron = 4 + 1*4 = 8

Answer: 8

5)

Main group elements try to attain octet configuration that is have 8 electrons in their valence shell

Answer: 8

6)

Double bond has 2 pair of electrons between 2 atoms

Single bond has 1 pair of electrons between 2 atoms

triple bond has 3 pair of electrons between 2 atoms
