BF3 is non planer and also trigonal planer shape and is symmetrical with all respects. And no contain free unpaired electron because Florine is very electro negative dipole moment is 0.

Since fluorine is more electronegative than boron,each B-F bond in BF3 is polar and three bond moments are equal. However the symmetry of trigonal planer shape means that the three bond moments exactly cancel one another. Thats why it is non polar because net diople moment is 0.

A liquid is a state of matter. There being three states of matter, namely, solid, liquid, and gas. They all have their particular features and properties.Liquid is used to indicate formation of liquid substances in a reaction.Water is liquid.

By “aqueous,” we actually mean a solution where the solvent is water and some compound is dissolved in it.'Aqueous' in a chemical equation indicates that the material dispersed in water (a solution in water). For example, when we pour sodium hydroxide solution into dilute hydrochloric acid, we get an aqueous solution of sodium chloride.

Hydrogen bond is stronger than covalent bond , as it forms bonds between highly electronegative atoms.

Anshika Choudhary 8 years, 2 months ago

A hydrogen bond can be easily broken , whereas a covalent bond is much stronger

Rahul Poddar 8 years, 2 months ago

Hydrogen bond is also covalent bond a special case where only hydrogen form covalent bond highly electronegative elements so, their is no difference in covalent and hydrogen bond ex- H2O it has covalent bond as well as hydrogen bond

Isotopes are each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an elements.

Carbon has isotopes. There are three isotopes of carbon: carbon-12, carbon-13 and carbon-14. The numbers that are after the carbon refer to the atomic mass.
