Answer: five carbon atoms forms a ring. In adjacent two carbon atoms
An hydroxyl group (-OH) is attached. Molecular formula is
C5H8(OH)2
Explanation:
Answer:
a)decrease
b)increase
c)smaller
d)smaller
Explanation:
Ionization energy decreases down the group due to increase in the atomic radius. The distance between the outermost electron and the nucleus increases hence the nuclear attraction for the outermost electrons become smaller and the ionization energy also become smaller as electrons are now easily removed from the outermost shell.
Hence the group of answer choices provided above.
