A.
a - 4, b - 3, c - 1 , d - 2
B.
a - 2, b - 1, c - 4 , d - 3
C.
a - 1, b - 2, c - 3 , d - 4
D.
a - 3, b - 4, c - 2, d - 1
Answer :
a - 3, b - 4, c - 2, d - 1
Solution :
$$\left( {\text{A}} \right):C{H_{4\left( g \right)}} + 2{O_{2\left( g \right)}} \to C{O_{2\left( g \right)}} + 2{H_2}O$$ shows combustion reaction
$$\left( {\text{B}} \right):{H_{2\left( g \right)}} \to 2{H_{\left( g \right)}}$$ shows bond dissociation
$$\left( {\text{C}} \right):NaC{l_{\left( s \right)}} \to Na_{\left( g \right)}^ + + Cl_{\left( g \right)}^ - $$ shows dissociation of $$NaCl$$
$$\left( {\text{D}} \right):NaC{l_{\left( s \right)}} \to Na_{\left( {aq} \right)}^ + + Cl_{\left( {aq} \right)}^ - $$ shows dissolution of $$NaCl$$
