Mark out the correct decreasing order of ease of addition of halogen.
1
2
3
4
Explanation:
: As stability of alkene increases then the stability of addition of halogen in alkene increases. Stability of alkene $\propto$ No. of $\propto$ - hydrogen Hence, the order of decreasing are -

Wacker process is an industrial process of the oxidation of terminal alkenes. Which of the following represents a true statement about the product?
1 The product is an aldehyde with same number of carbon atoms as in the alkene
2 The product is a ketone with same number of carbon atoms as in the alkene
3 The product is an oxirane with same number of carbon atoms as in the alkene
4 The product is a terminal alcohol as the net reaction is hydration of an alkene
Explanation:
,b) : Wacker process is an industrial process of oxidation of terminal alkene - - The product is an aldehyele with same number of carbon atom as in the alkene. - The product is a ketone with same number of carbon atoms as in the alkene.
