Question

Ethylene reacts with sulphur monochloride to form:
(A) Ethyl chloride
(B) Ethylene chloride
(C) Mustard gas
(D) Ethylidene chloride

Answer 1

Hint:Ethylene is a hydrocarbon which is colourless and flameless in nature. It has a musky and sweet odour when it is in its pure state. It is an unsaturated hydrocarbon which is \[s{{p}^{2}}\] hybridised. It helps in determining the sex of flower, ripening of fruit and pollination also.

Complete step-by-step answer:when ethylene is reacted with sulphur monochloride the formation of mustard gas takes place. The equation for it is the following:
\[10{{C}_{2}}{{H}_{4}}+5SC{{l}_{2}}\to {{({{C}_{4}}{{H}_{8}}C{{l}_{2}})}_{5}}+5S\]
In the Levinstein process the ethyne is reacted with disulphur dichloride and the formation of mustard gas occurs on treating them. the reaction is the following:
\[16{{C}_{2}}{{H}_{4}}+8{{S}_{2}}C{{l}_{2}}\to 8{{(ClC{{H}_{2}}C{{H}_{2}})}_{2}}S+S\]
Mustard gas is also known as mustard agent or sulphur mustard which is used as a chemical warfare agent and causes irritation and blistering of skin. So the correct answer for this question is option (C). The formation of ethyl chloride takes place by reacting ethylene with hydrogen chloride under the presence of a catalyst called aluminium chloride. Ethyl chloride tends to get dissolved in alcohol and ether. The formation of ethylene chloride takes place by treating ethylene and chlorine together which thereby converted to vinyl chloride at the temperature of 500C in the presence of catalyst.

So the correct answer is option (C).

Note:Ethylene is used widely in plants as it breaks the dormancy of seed, helps in flowering, it stimulates the abscission of leaves. It also speeds up the senescence of flowers and leaves. It also helps in inducing the feminising effects in plants. The lamps of ethylene are used in the development of colour and fruit ripening.
