Question

(c) $h_3c - ch_2 - ch_2 - ch - ch_2 - ch_2 - oh$
$h_2c - ch_3$
spell out the full name of the compound.

Explanation:

Step1: Identify the longest carbon chain

The longest carbon chain has 7 carbon atoms.

Step2: Locate the substituents

There is an ethyl group ($\ce{-CH_{2}CH_{3}}$) on the 4th carbon atom.

Step3: Name the compound

Since it is an alcohol (has $\ce{-OH}$ group), the suffix is -ol. The parent chain is heptane (7 - carbon alkane), so the name is 4 - ethylheptan - 1 - ol.

Answer:

4 - ethylheptan - 1 - ol
