Partial racemization

It is a reduing agent....

Ya thats right...... i didnt use that approximation

Hey the points you given are right and you oncluded it s SN¹ then why you choose answer (a). SN is nucleophilic substitution so the answer is (b) nucleophilic substitution.

(P^o - P)/P^o = n₂/ (n_¹+n₂)

From this we can calulate n₂ which is equal to 1.089 from this we can get molality which is also 1.089

The important thing is we're taking density of water as 1g/ml.

Ther are some nucleophiles which have more than one nucleophilic centre, simple example is CN^- and NC^-.They ar called ambidentate nucleophiles.

Eg:CN^-, ^-NO_2,

For the fusion to take place the nucleus has to come very close.. Since the H atom is very small there will be greater nuclear repulsion.. We need more KE to overcome that repulsion... I think thats why it's vary hard for nuclear fusion of H atom........

Most of the natural process are highly efficient

Hybridisation of XeF₂ is sp³d whose structure is trigonal bipyramidal. In which the 3 lone pairs are present in equatorial position and the 2 flourine atoms are present in axial position. It doesnt mean that it is non polar. Rather it is polar bcz of the three lone pairs...

The imp step in aldol condensation is the formation of carbanion. carbanion is formed only if there is a

-hydrogen. In acataldehyde we've alpha hydrogen hence it forms carbanion which then reacts with benzaldehyde to give you the product.

If u r really good in basics go for morrison & boyd.. Try Rxn mech &prob in organic chemistry by R chattopadhyay

For stereochemistry the best book is eliel... for inorgani J D Lee is enough for some basic things if u need some advance text go for cotton and wilkinson

Kishore s correct.... Aromatic aldehdes wont undergo for eg benzaldehyde
