    In alcohol electron releasing alkyl gr is present which releases electron density towards oxygen and thereby makes OH bond less polar hence it becomes difficult to release H+ ion from alcohol than water

    In Nucleophilic substitution reactions aryl halides (haloarenes) are less reactive due to the following reasons: The primary reaction of aromatic compounds is Electrophillic addition because of the aromaticity which benzene posseses. Benzene itself acts as a nuceophile which isn't in the favour of nucleophilic substitution reactions. Also, in haloarenes the C-X bond (carbon halogen bond) has a double bond characters due to the lone pair of halogens. Whereas the C-X bond in alkyl halides is comparitively weaker with respect to the resonance stabilised C-X bond in aryl halides. Thus we can conclude that haloalkanes are more reactive than haloarenes.

    α- glucose and β- glucose are two cyclic hemiacetal forms of glucose which differ only in the configuration of hydroxyl group (-OH) at anomeric carbon. Such isomers are called anomers. The six-membered cyclic structure of glucose is called pyranose structure. α-D-glucose and β-D-glucose are stereoisomers, they differ in 3-dimensional configuration of atoms/groups at one or more positions.Anomers are capable of interconverting in solution. All cyclic structures of monosaccharides exhibit anomeric α (down) and β(up) versions. These differences occur at the anomeric acetal carbon (the only carbon with two C−O bonds.

    All the questions come from NCERT. Even if you cannot find the answer directly there, you can always find a hint from where the question has come. A single word or line may have the answer which has to be elaborated by you with your understanding and answer it in the paper in exam.
