(d) IUPAC name is localid="1652762698568" $2 b r o m o b e n z a l d e h y d e$ .

Step by step solution

Part (a) Step 1: Given Information

We need to find the IUPAC name of the compound.

Part (a) Step 2: Explanation

We are given a compound in which $- C H O$ group is present and we know that it is higher Preference group that's why counting start from this group side .

Therefore, IUPAC name is $p r o p a n a l$ .

Part (b) Step 1: Given Information

We need to find the IUPAC name of the compound.

Part (b) Step 2: Explanation

We are given a compound in which $C = O$ group is present . then we should take a long chain and Ensure that $- C H O$ group is near. that's why counting will start from right part Therefore , the IUPAC name is $2 m e t h y l p e n t - 3 - o n e$

Part (c) Step 1: Given Information

We need to find the IUPAC name of the compound.

Part (c) Step 2: Explanation

We are given a compound in which $C = O$ group is present and we know that it is higher preference than other groups that's why counting is start from this group carbon that's why the IUPAC name is $3, 4 d i m e t h y l c y c l o h e x e n o n$ .

Part (d) Step 1: Given Information

We need to find the IUPAC name of the compound.

Part (d) Step 2: Explanation

We are given a compound in which $- C H O$ group is present and that group is higher preference in this compound and counting will start from this. that's why the IUPAC name is $2 B r o m o b e n z a l d e h y d e .$
