Question:
(i) Differentiate between ionic, metallic, covalent and dipole-dipole bonds. Provide examples in each case.
(ii) With regard to electronic con?guration, what do all the elements in Group VII of the periodic table have in common?
(iii) Describe why hydrogen ?uoride (HF) has a higher boiling temperature than hydrogen chloride (HCl) (19.4ºC vs. - 85ºC), even though HF has a lower molecular weight.
(iv) On the basis of the hydrogen bond, explain the anomalous behaviour of water when it freezes. That is, why is there volume expansion upon solidi?cation?
(a) Copper has an atomic radius of 0.128 nm, a face-centered cubic crystal structure and an atomic weight of 63.5 g/mol. Compute
(i) the volume of a unit cell of copper
(ii) the atomic packing factor
(iii) the theoretical density of copper.
Structure of Aldehydes and Ketones Carbonyl carbon atom is connected to three atoms by sigma bonds. As these bonds use Sp 2 -orbitals, they found in the same plane and are 120°
Electronic displacement in covalent bonds It is examined that most of the attacking reagents all time possess either a positive or a negetive charge, hence for a solution to op
What are molecular orbitals? How are they formed? What does molecular orbital theory states? what is the significance of molecular orbital theory? Ans) Molecular orbitals are for
Number of electron does species have The H2 2- ion can be conceived to result from the combination of two hydride ions (H-). This species have four electrons; two occupy the b
Yes....because at boyles law....ideal gas equation is used and z=1 for PV=nRT
positive analysis radical
how does molar volume varies with: a) a decrease in temperature d) an increase in pressure
Q. Use of Halides of Boron? Boron trihalides of the type BX3 exist for all the four halogens. Boron trifluoride can be prepared on a large scale by the fluorination of boric ox
A solvated electron is a free electron in (solvated in) a solution, and is the least possible anion. Solvated electrons happen widely although they are often not practical directly
Deodorants: Just as the name suggests, deodorants are applied basically to mask the body odour. The body odour provides from the bacterial action subsequent perspiration. Hence
