Decide whether each of the following reaction involves oxidation reduction reaction or not. If it does,identify which species is oxidised and which gets oxidised?
\({ 4CH }_{ 3 }-\overset { \overset { O }{ || } }{ C } -{ CH }_{ 3 }+LiAl{ H }_{ 4 }={ 4H }_{ 2 }O\rightleftharpoons { 4CH }_{ 3 }-\overset { \overset { OH }{ || } }{ CH } -{ CH }_{ 3 }+LiOH+Al({ OH })_{ 3 }\)
