Q. 12.1 - An Introduction to General, Organic, and Biological Chemistry

Question

Give the IUPAC name for each of the following

Step-by-Step Solution

Answer

(a) The name of the compound is ethanol.

(b) The name of the compound is $\mathrm{butan}-2-\mathrm{ol}$

(c) The name of the compound is $\mathrm{pentan}-2-\mathrm{ol}$.

(d) The name of the compound is $2-\mathrm{bromo}-\mathrm{benzen}-1-\mathrm{ol}$

Part (a) Step 1: Given Information

We are given the compound structure i.e.  and we have to find out the IUPAC name of the compound.

Part (a) Step 2: Explanation

The compound contains C carbon, H hydrogen, and O oxygen and only one chain is here, so the name of the compound is ethanol.

Hence, the name of the compound is ethanol.

Part (b) Step 1: Given Information

We are given the compound structure i.e.  and we have to find out the IUPAC name of the compound.

Part (b) Step 2: Explanation

The compound contains C carbon, H hydrogen, and O oxygen with one chain and one branching on the second carbon, so the name of the compound is$\mathrm{butan}-2-\mathrm{ol}$.

Hence, the name of the compound is$\mathrm{butan}-2-\mathrm{ol}$ .

Part (c) Step 1: Given Information

We are given the compound structure i.e.  and we have to find out the IUPAC name of the compound.

Part (c) Step 2: Explanation

The compound contains C carbon, H hydrogen, and O oxygen and has one chain and one branching on the second carbon, so the name of the compound is$\mathrm{pentan}-2-\mathrm{ol}$.

Hence, the name of the compound is$\mathrm{pentan}-2-\mathrm{ol}$.

Part (d) Step 1: Given Information

We are given the compound structure i.e.  and we have to find out the IUPAC name of the compound.

Part (d) Step 2: Explanation

The compound contains C carbon, H hydrogen, Br bromine and O oxygen and only one ring is here, so the name of the compound is $3-\mathrm{bromo}-\mathrm{benzen}-1-\mathrm{ol}$.

Hence, the name of the compound is$3-\mathrm{bromo}-\mathrm{benzen}-1-\mathrm{ol}$.
