name compound

Attached is the IR, NMR and Mass spec of a compound included is the formula molecular weight. Write a structure consistent with data, draw a molecular ion. I have already circled the OH Peak.

determine structure

I have tried to work out the following problem. Attached to this is a file that show NMR, IR and Mass spec info. I have come up with what I think the compound is but it does not work because the formula has more than one o I have circled the carbonyl peak as well as the sp3 C-H peak.

need detailed refresher on how to solve reation problem

if you had 3grams of 4-chlorobenzoic acid dissolved in ether, how many milliliters of a 4M NaOH solution would be needed to react with it all?

What is the name of this Alkyne

What is the name of this Alkyne? CH3CH2C=C (the above = symbol should be 3 lines)

Chemical Reactions
