Short Answer

Expert verified

(a) IUPAC name is $3 m e t h y l p e n \tan a l$

(b) IUPAC name is $2 p e n t e n o n e$

(d) IUPAC name is $3 c h l o r o b e n z a l d e h y d e$

Step by step solution

Part (a) Step 1: Given Information

We need to find the IUPAC name of given compound.

Part (a) Step 2: Explanation

We are given a molecule in which we see there is a $C = O$ group there has a higher preference to other groups that s why counting will start from that group so the IUPAC name of this molecule is $3 m e t h y l p e n \tan a l$

Part (b) Step 1: Given Information

We need to find the IUPAC name of given compound.

Part (b) Step 2: Explanation

We are given a molecule in which we see there is a $C = O$ group there has a higher preference to other groups that s why counting will start from that group or its near carbon so the IUPAC name of this molecule is $2 p e n \tan o n e$ .

Part (c) Step 1: Given Information

We need to find the IUPAC name of given compound.

Part (c) Step 2: Explanation

Part (d) Step 1: Given Information

We need to find the IUPAC name of given compound.

Part (d) Step 2: Explanation

We are given a molecule in which we see there is a $- C H O$ group there has a higher preference to other groups that s why counting will start from that group and move toward 2nd group so the IUPAC name of this molecule is $3 c h l o r o b e n z a l d e h y d e$
