Answer 1

Answer:

total sigma =18

pi = 4

Explanation:

a) sigma = 3

pi = 1

b) sigma = 4

pi = 0

c) sigma = 11

pi = 3

Answer 2

Answer:

(a) Acetylene C2H2 contains 3σ bonds and 2π bonds. Total number of bonds =3+2=5.

(b) Ethylene C2H4 contains 5σ bonds and 1π bond. Total number of bonds =5+1=6.

c) Benzene C6H6 contain 6 sigma bonds 3 pie bonds 3 double bonds Total number of bonds=6+3+3=12
