in sunlight mainly gives:
a) 1-Bromo-2-methyl butane
b) 2-Bromo-2-methyl butane
c) 2-Bromo-3-methyl butane
d) 1-Bromo-3-methyl butane
Which of the statements is correct?
I. Melting point of alkane increases with increase of C atoms and with increase in branching.
II. Boiling point of alkane increases with increase of C atoms but with increases with increase of C atoms but with decrease in branching.
III. Cycloalkanes have lower boiling point than normal alkane with same number of C atoms.
IV. Alkenes have lower boiling point than same number of C atoms in alkanes.
