Give one chemical test to distinguish between the pair of compound :
Aniline and N-methyl aniline

Write structure of the compound whose IUPAC names are as follow:

2-Ethoxy-3-methylpentane.

Bring out the following conversion:
Acetophenone to 2-phenyl butan-2-ol.

Read the given passage and answer the questions number 1 to 5 that follow:
The substitution reaction of alkyl halide mainly occurs by S_N1 or S_N2 mechanism. Whatever mechanism alkyl halides follow for the substitution reaction to occur, the polarity of the carbon halogen bond is responsible for these substitution reactions. The rate of S_N1 reactions are governed by the stability of carbocation whereas for S_N2 reactions steric factor is the deciding factor. If the starting material is a chiral compound, we may end up with an inverted product or racemic mixture depending upon the type of mechanism followed by alkyl halide. Cleavage of ethers with HI is also governed by steric factor and stability of carbocation, which indicates that in organic chemistry, these two major factors help us in deciding the kind of product formed.
Predict the stereochemistry of the product formed if an optically active alkyl halide undergoes substitution reaction by S_N1 mechanism.

Alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses. Explain this fact.
