After nitrogen, the electronegativity decreases down the … Preparing for entrance exams? So I know the forces responsible for the boiling point are the vanderwale forces (depending on the mass of the molecules), and the hydrogen bonds. Bond angle: NH3 (107.8°) > PH3 (99.5°) > AsH3 (91.8°) ≈ SbH3(91.3°) > BiH3 (90°) Electronegativity of N is highest.

Ethanoic acid (CH3COOH) is a weak acid. Give reason. Boiling points of nitrogen family generally increases on moving down the group but boiling point of NH 3 is higher than PH 3 and AsH 3 due to hydrogen bonding. due to Hydrogen bonding in liquid state.The B.p of SbH3 is still higher due to high extent of van der waal forces. Register yourself for the free demo class from Boiling point of NH3 is more because of hydrogen bonding. Register Now, Hey there! Therefore, the lone pairs will be towards nitrogen and hence more repulsion between bond pairs. Arrange according to boiling point NH3, PH3, AsH3, SbH3, BiH3.

Identify compound X in the following sequence of reactions: Identify a molecule which does not exist. Favorite Answer. Structural Organisation in Plants and Animals. NH3 will have the highest boiling point because NH3 molecules can form hydrogen bonds with each other. We can then use our knowledge of these molecules to determine the intermolecular forces present. Give reason. Register yourself for the free demo class from The boiling point of butane is close to 0 degrees Celsius, whereas the higher boiling point of butanone (79.6 degrees Celsius) can be explained by the shape of the molecule, which creates an attractive force between the oxygen on one molecule and the hydrogen on … We compare the boiling point of NH3 … Students (upto class 10+2) preparing for All Government Exams, CBSE … Blog | You can study other questions, MCQs, videos and tests for NEET on … Dear The atomic radiusis: Find out the solubility of $Ni(OH)_2$ in 0.1 M NaOH.
