Question

Draw structure of 1,1,3methyl butanoic acid

Answer 1

There is a mistake in question that the name will be,

3-methyl butanoic acid.

As,

We have to give the numbering to carbon of carboxylic acid as first.

And in carboxylic acid 3 valencies are already filled.

4th valency will be filled by the carbon chain

So ,no subgroup can be attached on 1st carbon.

Answer:

Any compound of carbon can be drawn from its IUPAC name.

As,

☆ As we have to make main carbon chain of four carbons as 'but' is given.

☆ We have to attach 1 methyl groups on 3rd carbon as 3 methyl is given.

☆ we have to attach carboxylic acid as 'oic acid' is given.

So,

According to above the structure of the compound is given attachment.
