Question

Write the IUPAC name of the following organic compound.

CHOH = CCl - CBr- CCl = CHOH​

Answer 1

Answer:

2-bromo 3,4dichloro pentane-1,5 diol

Answer 2

Given, Organic compound :

CHOH = CCl - CBr- CCl = CHOH

1. There are five carbon atoms in the parent chain.
2. The primary functional group is Alcohol —OH group.
3. Cl, Br functional groups are to be substituents

So thus the IUPAC name of the organic compound is,

3-bromo-2,4-dichloropenta-1,5-diol

Alcohol group is the primary functional group, and is mentioned as ol. The number and location are represented by di, 1,5.

The bromo, chloro groups are arranged alphabetically with their location and number.

The longest carbon chain consists of five carbons, and hence the root word penta-.
