V.B.T. Worksheet
Valence bond Theory (V.B.T) was developed by Walter Heitler and Fritz London in 1927 and was later modified by Linus Pauling to take bond direction into account. Some of the question related to Valence bond theory are listed below: Questions: 1. The correct order of decreasing strength of overlapping is: (a) s –s > s – p > p – p (b) p – p > s – p > s – s (c) s – p> p – p > s – s (d) s – p > s – s > p – p 2. when Z-axis is molecular axis then -molecular orbitals are...

Chemical bond is the attraction between two or more atoms that allows the formation of chemical substances. The formation of bond is due to electronmagnetic force of attraction between opposite charges. There are three types of Chemical bond. They are : 1. Ionic bond 2. Covalent bond 3. Polar covalent bond Here you can find some question and answers related to chemical bonding. Questions: 1. Which of the following species are hypervalent: 1. (a) 1, 2, 3 (b) 1, 3 (c) 3, 4 (d) 1, 2 2. The expected shape of ion...

Interaction of a hydrogen atom with an electronegative atom, such as fluorine, nitrogen or oxygen, that comes from another molecule of chemical group is known as hrdrogen bond. Some of the question related to h-bond are listed below: Questions: 1. Which can have H-Bonding: (a) (b) (c) (d) All of these 2. Which does not have intramolecular hydrogen bonding: (a) Salicylaldehyde (b) O-nitrophenol (c) Ortho xylene (d) Ortho hydroxyl benzonic acid 3. Which is highly soluble in water...

Chemical bond can be defined as the force of attraction between two atoms which holds atoms and ions together in a unit. Electrovalent bond is a chemical bond in which atom loses an electron to form a positive ion and the other atom gains the electron to form a negative ion. Some of the questions related to Chemical bonding are listed below, with their answer. Questions: 1.An bond is formed under which condition mainly? (a) donate to non-metal (b) Energy must be released during bond formation (c) Energy must be adsorbed during...

Resonance can be defined as a way of defining delocalized electons with certain polyatomic ions and molecules, where bonding can’t be epressed by Lewis formula. Resonance is also a key component of valence bond theory. Some questions and their answers related to resonance are listed below: Questions: 1. Which is not true about resonance: (a) Here arrangement of atoms is same. (b) Resonating structures are shown by (c) Resonating structures differ in distribution (d) Resonance decreases stability 2. Which in not correct...
