Question

PLZZZ NAME t
HE FOLLOWING COMPOUND ACCORDING TO IUPAC

Answer 1

Answer:

See below.

Explanation:

1. Check for the longest chain. We can find the longest chain of 5 carbon atoms.

2. Check for functional groups. We can find the ketone group.

3. Assign numbers to the carbon atoms. Since the ketone group is nearer to the RHS, therefore, we start the number from the right hand side.

So,  we get,

A 5 carbon straight chain - Pentane

A ketone group at position 2.

Two double bonds at position 3 and 4.

Hence the IUPAC name will be,

pent-3,4-diene-2-one
