Answer:
Heat of fusion
Explanation:
The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat of fusion.
The formula for the heat of fusion is given by :
Where
n is no of moles
is molar heat of the substance
Hence, the correct answer is heat of fusion
Answer:
II
Explanation:
We must have a good idea of the fact that there are two mechanisms that come into play when we are discussing about the addition of hydrogen halides to alkenes. The first is the ionic mechanism and the second is the radical mechanism.
The ionic mechanism is accounted for by the Markovnikov rule while the radical mechanism occurs in the presence of peroxides and is generally referred to as anti Markovnikov addition.
The intermediate in anti Markovnikov addition involves the most stable radical, in this case, it is a tertiary radical as shown in the images attached. The most stable radical is II hence it leads to the major product shown in the other image.
