Explanation:
Alkanes are the simple hydrocarbons that have only carbon and hydrogen atoms attached to each other through single bonds.
General chemical formula of an alkane is 
, where n is any integer.
For example, if n = 5 then formula of the alkane will be as follows.
= 
= 
A suffix "-ane" is added in the name of an alkane. So, an alkane with five carbon atoms will be known as pentane.
Radioactivity or radioactive decay is the process that occurs when unstable isotopes or atoms release energy by emitting radiations such as ,gamma radiations, alpha radiations and beta radiations to attain stability. Therefore, in this case decay is likely to occur when a given atom has two many neutrons in its nucleus in order to attain stability.
Answer:Methyl benzoate has a very high boiling point i.e. 199°C.Therefore a water-cooled condenser is not advisable as it might crack the condenser tube.So in such cases air condenser tube is normally used for such distillation procedure.
There are 32 :) hope is helps
