MOLECULAR POLARITYFIELD NOTE 132 / 175

Is Methyl Acetate (C3H6O2) polar or nonpolar?

Methyl Acetate (C3H6O2) is polar because its ester has a carbonyl C=O bond and a second C–O–C oxygen link.

THE ANSWERPolar.

Methyl Acetate · trigonal planar at carbonyl C; bent at ester O

THE REASONING

Why C3H6O2 is polar

Methyl acetate has the structure CH3–C(=O)–O–CH3. The carbonyl oxygen and the single-bonded ester oxygen occupy different positions; their polar bonds do not form equal opposite vectors across the molecule.

A USEFUL DISTINCTION

What to notice

Methyl acetate and acetic acid share a carbonyl plus another oxygen, but the ester ends with –O–CH3 rather than –O–H. That changes connectivity and hydrogen bonding, not the presence of a net dipole.
