Based on octet rule, atoms tend to give or take electrons by forming an ion until it has eight valence electron.
An atom with valence electron less than 4 will tend to lose the electron and form a cation. Boron is an atom with atomic number 5 which have 3 valence electron. So, Boron should lose 3 of it valence electron and form a +3 cation.
Answer : Option D) Sodium Chloride.
Explanation : Boiling point is the temperature at which the vapor pressure of a liquid is equal to the external pressure surrounding the liquid.
On the basis of bonding, the compound which has highest boiling point is sodium chloride.
Alcohol are found to have boiling point approximately as 78.37 °C.
Glucose usually melts at 146 °C.
Water boils at 100°C.
Sodium chloride has boiling point 1413 °C.
So, it is easy to identify that NaCl (sodium chloride) has highest boiling point amongst the given choices.
Answer:
