Ethyl alcohol reacts at a faster rate wi...

Ethyl alcohol reacts at a faster rate with `HI` than with `HCI` in forming the corresponding ethyl halides under identical conditions mainly because-

A

[A] `HI`, being a stronger acid, protonates ethyl alcohol at oxygen much better and helps substitution

B

[B] the bond length in `HI` is much shorter than that in `HCI`

C

[C] `I^(-)` is a much better leaving group

D

[D] `I^(-)` is a much better nuclephile than `CI^(-)`

Assertion : Newton's rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright. Reason : This is because the reflections in these cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.

(b) The absolute configuration of product is opposite to that of the reactant when an optically active substrate is used. (c) The used shows first order kinetics. (d) The rate of the reaction depends markedly on the nucleophilicity of the attacking reagent. (e) The mechanism is one step. (f) Carbocations are intermediate. (g) Rate prop [Alkyl][halides] (h) The rate of the reaction depends on the nature of the leaving group.

Explain the following observations: (a) Azide ion (N_(3)) react with 2- bromopentane thousand times faster than with neopentyl bromide in a S_(N)2 reaction through former isa secondary halide while latter is primary. (b) What will happen to teh stereochemistry of product of the following reaction: (c) What will happens to the rate if the concentration of alkyl bromide in (b) is doubled? (d) Wha will happen to the rate if the concentration of azide ion in (b) is doubled? (e) How the sign of optical rotation of reactant and product are related in (b) (f) When allowed to stand in dilute H_(2)SO_(4) laevo-rotatory 2-butanol slowly loss optical activity.
