Chlorine can be converted into chloride ion more easily as compared to fluoride ion resulting from fluorine. Explain.

Acid chlorides can be use to prepare aldehydes and ketones. Can you prepare acetone from acetyl chloride? Explain.

F centre is an example of metal excess defect due to the presence of extra cations at interstitial sites. Zinc oxide is white in colour at room temperature, on heating it loses oxygen and turns yellow. ZnO overset("Heat")toZn^(2+)+(1)/(2)O_(2)+2e^(-) Now there is excess of zinc in the crystal and its formula becomes Zn_(1+x) O. the excess of Zn^(2+) ions move to interstitial sites and the electrons to neighbouring interstitial sites. There are many solids which are difficult to prepare in the stiochiometric composition and contain less amount of the metal as compared to stiochiometric proportion. a typical example of this type is FeO which is mostly found with a composition of Fe_(0.95) . it may actually range from Fe_(0.96) O. Q. In Fe_(0.95) O:

Assertion: The conductivity of an electrolyte is very low is compared to a metal at room temperature. Reason : The number density of free ions in electrolyte is much smaller as compared to number density of free electrons in metals. Further, ions drift much more slowly, being heavier.

Assertion: When KI solution is added to AgN0_(3) solution, negativity charged sol results. Reason: Negative charge of Agl sol is due to preferential adsorption of iodide ions from the dispersion medium.

Assertion : p-fluoroanilinium ion is more acidic than anilinium ion Reason : Electron density in the N-H bond of p-fluoroanilinium ion decreases and releases a proton more readily than from anilinium ion

When 3-methylbutan-2-ol is treated with HBr,the, following reaction takes place: Give a mechanism for this reaction. (Hint: The secondary carbocation formed in step If, the arranges to a more stable- tertiary carbocation by a hydride ion shift from 3rd carbon atom.)

1.Aqueous copper sulphate solution (blue in colour) gives i) a green precipitate with aqueous potassium fluoride and ii) a bright green solution with aqueous potassium chloride. Explain these experimental results.

Consider the case hydrogen Chloride molecule [HCl] The chlorine atom with a higher electronegativity attract the shared pair of electrons towards its nucleus. As a result the chlorine atom in hydrogen chloride develops a partial negative charge delta^- (delta negative) and hydrogen atom develops a partial positive charge delta^+ (delta positive) it can be represented below.
