Question

The general formula for alcohol series is $C_n{H}_{2n+1}OH$. Which is the formula of the alcohol containing four carbon atoms?

• A. $C_5{H}_{11}OH$
• B. $C_4{H}_{9}OH$
• C. $C_4{H}_{8}OH$
• D. $C_3{H}_{8}OH$

Answer 1

The correct option is B $C_4{H}_{9}OH$

The general formula for alcohol series is $C_n{H}_{2n+1}OH$. The formula for alcohol contains four carbon atoms is
$C_n{H}_{2n+1}OH=C_4{H}_{2\left(4\right)+1}OH=C_4{H}_{8+1}OH=C_4{H}_{9}OH$.
Hence, the correct answer is option (b).
