Answer 2

Given :

4-ethyl-2,6-dimethyl-dec-4-ene

To Find :

Number of sigma and pi bonds.

Solution -

IUPAC name of the given compound is 4-ethyl-2,6-dimethyl-dec-4-ene

The name suggests the following things -

• The longest carbon chain has 10 carbon atom (dec = 10)

• In fourth carbon an ethyl ($C_2H_5$) is attached
• In second and sixth carbon methyl (CH$_3$) group is present

As per the structure of the compound (refer to the image attached), we can see that -

Number of Sigma bonds = 29

Number of pi bonds = 1
