Read the given passage and answer the question : Organic compounds containing amine as functional group are present in a vivid variety of compounds, namely amino acids, hormones, neurotransmitters, DNA, alkaloids, dyes, etc. Drugs including nicotine, morphine, codeine and heroin, etc. which have physiological effects on humans also contain amino group in one form or another. Amines are basic because of the presence of lone pair of electrons on nitrogen. Addition of nitrogen into an organic framework leads to the formation of two families of molecules, namely amines and amides. As chemistry students, we must appreciate the versatility of nitrogen. Give one point of difference between acidic and basic amino acid.
Acidic amino acids- They have more number of carboxyl groups than amino groups. whereas
Basic amino acids- have more number of amino groups than carboxyl groups.

View Full Answer(1)Read the given passage and answer the questions that follow : The substitution reaction of alkyl halide mainly occurs by or
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
reactions are governed by the stability of carbocation whereas for
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. Write the structures of the products formed when ethoxybenzene is treated with HI.
Products formed when ethoxybenzene is treated with HI are
C2H5I + C6H5OH
View Full Answer(1)Iodoform test is not given by
Option: 1 Hexan-2-one
Option: 2 Hexan-3-one
Option: 3 Ethanol
Option: 4 Ethanal
Iodoform test is not given by Hexan-3-one, since it is not methyl ketone
Hence option B is correct
