Answer #1

Since we are getting peak at 151 & 153 which are M And M+2 peak, which are of equal intensity, it means Br atom is present.

Mass of Br atom=80

Left mass of alkyl chain=151-80=71

Since their are 5 peaks in C-nmr and 5 in also H nmr with splitting pattern.

It means their are five type of carbon.

So the formula of compound is CH3(CH2)4Br pentane bromide...

I hope it helps you, please give me a positive feedback ?
