well you forgot that Alcohols are also oxidized to carboxylic acid in case of primary alcohol. hence DThe compound hex-3-en-1-ol, P, has a strong ‘leafy’ smell of newly cut grass and is used in
perfumery.
CH3CH2CH=CHCH2CH2OH
P
What is produced when P is treated with an excess of hot concentrated acidic KMnO4?
A CH3CH2CH(OH)CH(OH)CH2CH2OH
B CH3CH2CH=CHCH2CO2H
C CH3CH2CHO and OCHCH2CH2OH
D CH3CH2CO2H and HO2CCH2CO2H
i get the answer as CH3CH2CO2H and COOHCH2CH2OH which is not listed....can anyone explain my mistake please!!!

how can you use water for drying ? CaCl2 absorbs water from ammonia n it is highly used for drying of amines ammonia alcohols ketones etcAoa/Hi.
Is calcium chloride used as a drying agent to dry ammonia(gas)? Why? ..and why isn't water used?
This is regarding a mistake i did in paper 4.
there was a diagram for exorthermic reaction, and we had to complete it by writing the products and enthalpy change.
instead of writing the real products i wrote only PRODUCTS. Because i was confused!
Will that score any mark?? or do we have to write the specific products to gain the mark?
Thank you.
