Question

How many $2^o$ Hydrogen atoms are present in the given following compound?

• A. 2
• B. 5
• C. 7
• D. 8

Answer 1

The correct option is C 7

• There are 10 $s{p}^2$ hybridized carbon atoms.

7-Carbon atoms are without any substituents$⟹$ 7 - Hydrogen atoms attached to it.

2-Carbon atoms are common to ring which has no Hydrogen atoms attached to it.

1-Carbon atom is having $Cl$ as a substituent and hence no hydrogen atom.

• Hence, there are 7- $2^o$ Hydrogen atoms.
