Process of conversion of wood into coal by biochemical process, taking over millions of years is called:
-
catenation
-
carbonation
-
pyrolysis
-
destructive distillation
The Process of conversion of wood into coal by biochemical process is known as Carbonization. Coal burns cleaner than wood burning coal was easier because coal burned longer than wood.
Carbonization is the term for the conversion of an organic substance into carbon or a carbon-containing residue through pyrolysis or destructive distillation. It is often used in organic chemistry with reference to the generation of coal gas and coal tar from raw coal.

-
$C{O} _{2}$
-
$S{O} _{2}$
-
${H} _{2}$
-
$N{O} _{2}$
Hence, the correct option is C.

When super heated steam is passed through hot wood charcoal then reaction takes place as
${ C } _{ 12 }{ H } _{ 22 }{ O } _{ 11 }\xrightarrow { \quad \quad Conc.{ H } _{ 2 }S{ O } _{ 4 }\quad \quad } 12C+11{ H } _{ 2 }O$
Which of the following is obtained by the above reaction?
-
Animal charcoal
-
Sugar charcoal
-

An infra-red spectrum shows a broad peak at $3000$ $cm^{-1}$ and a strong peak at $1710$ $cm^{-1}$. Which substance could have produced this spectrum?
-
Methyl propanoate
-
Propan-$2$-ol
-
Propanoic acid
-
Propanone
Multiple Answer question
Instead of using plastics, these/this can be used to avoid pollution :
-
Jute bags
-
Paper bags
-
Cloth bags
-
Poly bags
Jute bags, Paper bags, and cloth bags are all biodegradable substances and decay overtime but poly bags degrade in hundreds of years and causes pollution. Thus, they can be used in place of plastic bags.
