Question

What is the formula of tertiary butyl alcohol?

• A. $C{H}_3-CH\left(C{H}_3\right)-C{H}_2-OH$
• B. $C{H}_3-(C{H}_2{)}_{2}OH$
• C. $C{H}_3-CH\left(OH\right)-C{H}_2-C{H}_3$
• D. $(C{H}_3{)}_{3}C-OH$

Answer 1

The correct option is D $(C{H}_3{)}_{3}C-OH$

Option a and b is an example of primary alcohol as $-OH$ group connected to primary carbon (connected to one carbon atom or number of H atoms attached to $s{p}^3-C$ is 2).

Option c is an example of secondary alcohol as $-OH$ group connected to secondary carbon (connected to two carbon atom or number of H atoms attached to $s{p}^3-C$ is 1).

Option d is an example of teriary butyl alcohol as $-OH$ group connected to tertiary carbon (connected to three carbon atom or number of H atoms attached to $s{p}^3-C$ is 0).
$(C{H}_3{)}_{3}C-OH$
