00:01 Hi, in this question we need to give the iupac name of the following compound.

00:04 So it is 1 2 1 1 2 3 4 5.

00:11 So it will be 3 -bromopentyl -ethyl -methyl -amine.

00:27 So this is 3 -bromopentyl -ethyl -methyl -amine.

00:35 The second part of the question is we need to write the condensed structure of o -n -h -l -ethyl group.

01:00 So this can be written as cl -c6h4 -c0 -nh -ch2 -ch3.

01:10 Then the third part of the question that is we need to write the iupac name for the compound o -e -t methyl group is there.

01:24 So this is 1 2 3 4 5.

01:30 So it is penta right.

01:33 So ethyl 2 -methyl -3 -oxopentanoate.

01:45 So this is the iupac name.

01:47 So ethyl 2 -methyl -3 -oxopentanoate right.

01:54 Then the d part.

01:57 So here they have given ch3 -ch2 -c double bond o -n -ch3 twice.

02:08 This is n ,n -dimethyl -amide which is converted to enolate ion form.

02:25 What is the reagent used for this? that is lda.

02:29 The lda is lithium isopropyl amine.

02:39 This is the structure of lda.

02:40 This lda is used to convert n ,n -dimethyl amide to enolate form.

02:46 Then next part of the question that is we need to iupac name...
