Jagriti attended Class 12 Tuition

"From past 3 years she serves as a teacher. She is actually a brilliant and intellectual person. But teaching as a profession is not limited to just giving knowledge, one should be acquainted to shape and mould students for there golden future, and this point of time she (saloni goyal) is well organised in her own. She is enthusiast and good learner as well. My kids are her students and I know she is best. Believe is the first key to any path choosen. Thanks. "

With aq KOH there would be an elimination reaction and with ethanolic KOH there would be substition of OH on Br place. One should remember that with alcoholic KOH always alcohols are formed.

Arrange the following in the increasing order of solubility in water.
 MgCl2, CaCl2, SrCl2, BaCl2

the smaller the cation more easily it will get solublised. thus, MgCl2 > CaCl2 > SrCl2> BaCl2

b) lattice enthalpy is the enrgy to break out bonds to release atoms. as Li is small and F itself is small so the bond will be small and thus more energy will be required to break the bond and thus the enthapy would be higher.

a) alkali metals have only 1 electron in their last valence shell so thats why they show +1 oxidation state by attaining the noble gas configuration.

b) if the electrons are single in the last shell they possess very high energy so as the metal gets heated up they excite to the higher energy level by attaining some energy and when they re-emit the absorbed energy the color is imparted.

c) Li+ is very small in size. and its in general that a smaller anion is stablized by smaller cation. so being oxide O2- and peroxide 022- the smaller and the larger anion respectively. therefore Li+ will form oxide not superoxide.

d) reducing agents are those which reduces others but oxidise themselves. oxidation is loosing of electron so because Li readily forms Li+ on loosing one electron thus is a reducing agent.

Down the group solublity decreases due to the increaasing size of alkali earth metal. Therefore, the smaller alkali earth metals like Be and Mg are soluble in water and thus their sulphates are more soluble.
