Dedicated to all moms

C=O group is dad

O atom is mom

Carbonyl is dad and oxygen mom hence c labelled methyl has higher chemical shift  and gets a little more attention

NMR IS EASY

A chemical has Formula: C₅H₁₀O₂

C₅H₁₀O₂
Rule 2, omit O, gives C₅H₁₀
5 – 10/2 + 1 = 1 degree of unsaturation.
Look for 1 pi bond or aliphatic ring.

IR

The band at 1740 indicates a carbonyl, probably a saturated aliphatic ester. The bands at 3000-2850 indicate C-H alkane stretches. The bands in the region 1320-1000 could be due to C-O stretch, consistent with an ester.

 Structure answer

This is the structure. See if you can assign the peaks on your own.

NMR answer

C has a higher chemical shift than D because it’s closer to a more electron-withdrawing functional group.

Carbonyl is dad and oxygen mom,  hence c has higher chemical shift  and gets a little more attention in proton nmr

WHAT HAPPENS WHEN A CHLORO IS INTRODUCED

WHEN THERE IS ONE METHYL

WHEN THERE ONE CH2 SHORT 

WHEN MOM HAS ONE MORE CH2
