Question

Two opposite charges separated by a given distance, no matter their relative orientation and the medium they are in, have the same energy of interaction.

	True
	False

Pentane (CH₃CH₂CH₂CH₂CH₃) is expected to boil at a lower temperature than propane (CH₃CH₂CH₃).

	True
	False

Answer 1

Solution :-

1) Two opposite charges separated by a given distance, no matter their relative orientation and the medium they are in, have the same energy of interaction. = True

because energy is directionaly proportional to the productof opposite charged divided by distance between the charges.

2) Pentane (CH₃CH₂CH₂CH₂CH₃) is expected to boil at a lower temperature than propane (CH₃CH₂CH₃). = False

Because as the number of carbon atoms increases in the straight chain alkanes the boiling points of the alkane increases therefore pentane have higher bopiling point than propane.
