if someone got 80% in term one, passed term 2 practical but failed in term 2 theory cbse class 12th will they be considered pass or fail in 12th?

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.
 

Iodoform test is given by 
Option: 1 Pentan-2-one
Option: 2 Ethanoic acid
Option: 3 Pentan-3-one
Option: 4 Methoxymethane

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.
