Is the product pure? how do you know?  here is the results:  Starting mass of benzyl       1.0883g Collected mass of product    0.8957g  Product melting point     135˚C Mixture melting point (product mixed with benzoin)  114˚C Mixture melting point (product mixed with meso-hydrobenzoin)    135˚C

C2H3ClO2 is the formula, the solvent is CDCl3. Need help determining Integration values the multiplicity and the chemical the Peak refers to.

Please what molecule is this

Can you help me label this ir
