(a)
Interpretation- To identify the double bond
Concept Introduction-
Covalent bond is formed when electrons are shared between two non-metals. It can be of following type:
- Single bond − it contains one sigma bond
- Double bond − it contains one sigma and one pi bond
- Triple bond − it contains one sigma and two pi bonds.
(a)
Explanation of Solution
Double bonds is identified as one sigma and one pi bond.
Hence, double bond is labelled as
(b)
Interpretation- To identify the phenyl group Introduction −
Alkyl groups: these are derived when one hydrogen atoms is removed from
Example: Methyl
(b)
Explanation of Solution
Phenyl
Hence in the given molecule phenyl group is labelled as
(c)
Interpretation- To identify the methyl group
Introduction-
Alkyl groups: these are derived when one hydrogen atoms is removed from alkane molecule.
Example: Phenyl
(c)
Explanation of Solution
Methyl group
Hence methyl group is labelled as
(d)
Interpretation- To identify an asymmetric carbon.
Introduction-
Asymmetric carbon − Carbon atom when have four different group is asymmetric.
Example :
(d)
Explanation of Solution
The carbon atom labelled
(e)
Interpretation- To identify the propyl group
Introduction −
Alkyl groups: these are derived when one hydrogen atoms is removed from alkane molecule.
Example: Methyl
(e)
Explanation of Solution
Propyl group
Hence propyl group is labelled as
