HBr
Yes Bayers reagent is Alkaline and it gives syn addition of two -OH groups across the double bond but if acidified KMnO4 is taken then that will cleave the double bond and give a mixture of acids
treat benzene with CO/CuCl/AlCl3/HCl to make a benzaldehyde (i.e. add CHO on benzene ring), then Zn(Hg)/HCl to make toluene
2-Methyl-1-propanol is a primary alcohol and so will not react with Lucas reagent at room temperature.Cyclopentanol is a secondary alcohol and so will react with Lucas reagent in 3-5 minutes (solution turns cloudy). Cyclopentyl chloride is the result.1-Methylcyclopentanol is a tertiary alcohol and so will react immediately with Lucas reagent to produce turbidity. 1-Chloro-1-methylcyclopentanol is the result.
Hi, Iodoform test is used for the detection of methyl ketones as methyl ketones give positive iodoform test. In this test, methyl ketone is treated with iodine (I2) in the presence of base such as sodium hydroxide (NaOH) to give iodoform(CHI3 - a light yellow coloured ppt). Chemistry of iodoform test is: Secondary alcohols also give positive iodoform test because during the reaction conditions, it gets oxidized to a methyl ketone.

methylhexanoic
LiAlH4; H2O and NaBH4,H2O
Does not react. Because Tollens' reagent only works with aldehydes. Butanone is methyl ethyl ketone (MEK).

try it both ways see what happens...

It is not easy to break C-Cl bond as it is strong. Hence alkyl chlorides are not suitable for Grignard reagents.
It turns yellow
Produced N-methylformamide
