oops! it didn't come in the picture. 'B' is in the top-right corner

yes because amine forms salt with acid which is meta-active.

For the system of irreversible, unimolecular consecutive reactions, nitrile  amide  acid, for all acid concentrations below 4 N. At higher concentrations, k1 and k2 are of the same order, and, in the case of sulphuric acid, k1 becomes k2 at concentrations above 20 N. So, in case of conc. H2SO4 (95%) amide will be produced instead of acid.

In a ? (pi) bond formation, parallel orientation of the two p orbitals on adjacent atoms is necessary for a proper sideways overlap. Thus, in H2C=CH2 molecule all the atoms must be in the same plane. The p orbitals are mutually parallel and both the p orbitals are perpendicular to the plane of the molecule. Rotation of one CH2 fragment with respect to other interferes with maximum overlap of p orbitals and, therefore, such rotation about carbon-carbon double bond (C=C) is restricted. The electron charge cloud of the ? bond is located above and below the plane of bonding atoms. This results in the electrons being easily available to the attacking reagents. In general, ? bonds provide the most reactive centres in the molecules containing multiple bonds. Same goes for compounds containing oxygen and nitrogen (not all of them).

if you use excess of SO2Cl2 then only C6H5CHCl2 or benzal chloride will be formed.

chlorination will take place.. apart from the major chlorinated product, some minor polychlorinated products is likely to be found.

A body A starts from rest with an acceleration a1. After 2s, another body B starts from rest with an acceleration a2. If they travel equal distance in the 5th second after the start of A, then the ratio a1, a2 equal to ?

charge is a physical property of matter that causes it to experience a force when near other electrically charged matter.

volatile compounds have a high vapor pressure at ordinary, room-temperature conditions. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air............. like formaldehyde, with a boiling point of –19 °C (–2 °F), slowly exiting paint and getting into the air.
