Thioester are unpleasant smelling compounds that contain _____.

sulfur

Carbon double bonded to Oxygen is Polar. T or F

True; the double bond creates a polar covalent bond due to the difference in electronegativity between carbon and oxygen.

function of EDTA

EDTA is a chelating agent that binds metal ions, used in various applications including medicine and environmental remediation.

What is formic acid derived from?
