$$C_{2}^{2-}$$ is expected to be diamagnetic

$$O_{2}^{2+}$$ is expected to have a longer bond length than $$O_2$$

$$N_{2}^{+}$$ and $$N_{2}^{-}$$ have the same bond order

$$He_{2}^{+}$$ has the same energy as two isolated He atoms

carbon tetrachloride + methanol

carbon disulphide + acetone

benzene + toluene

phenol + aniline

The number of the nearest neighbours of an atom present in the topmost layer is 12

The efficiency of atom packing is 74%

The number of octahedral and tetrahedral voids per atom are 1 and 2, respectively

The unit cell edge length is $$2\sqrt{2}$$ times the radius of the atom

crushing followed by concentration of the ore by froth-flotation.

removal of iron as slag

self-reduction step to produce ‘blister copper’following evolution of $$SO_2$$

refining of ‘blister copper’ by carbon reduction

can also be prepared by reaction of $$P_4$$ and $$HNO_3$$

is diamagnetic

contains one N-N bond

reacts with Na metal producing a brown gas

‘invert sugar’ is prepared by acid catalyzed hydrolysis of maltose

‘invert sugar’ is an equimolar mixture of D-(+)-glucose and D-(-)-fructose

specific rotation of‘invert sugar’ is $$—20^\circ$$

on reaction with $$Br_2$$ water, ‘invert sugar’ forms saccharic acid as one of the products
