Identify the incorrect statement for glucose.

The value of conductivity of some selected materials at 298.15 K is given below. From the value
identify a semiconductor.

Answer the question on basis of passage given below:
Organic compounds containing carbon -oxygen double bonds ( \(C = O\) ) are called carbonyl compounds. These are highly polar molecules. Hence, their boiling points are higher than hydrocarbons and ethers. Aldehydes can be prepared from dehydrogenation or oxidation of alcohols and by reduction of acylhalides. Ketones are prepared by oxidation of secondary alcohols or by hydration of alkynes etc. Aldehydes and ketones undergo nucleophilic addition reaction with the number of nucleophiles such as HCN , NaHSO 3 ammonia derivatives. Carboxylic acids are prepared by the oxidation of primary alcohols, aldehydes and alkenes, by hydrolysis of nitriles. Carboxylic acids are more acidic than alcohols and phenols.
The correct sequence of reagents for the conversion of \(3\)-nitrobromobensene to \(3\)-nitrobensoic acid is:

Which of the following reagents are used for denaturation of alcohol?

The edge lengths of the unit cells in terms of the radius of spheres constituting fcc, bcc \& simple cubic unit cell respectively are:

Adsorption is surface phenomenon and it differs from absorption which occurs throughout the body of the substance which absorbs. In physisorption the attractive forces are mainly van der Waal forces while in chemisorption actual bonding occurs between the particles of adsorbent and adsorbed more easily on the surface of a solid as compared to the gases which are liquified with difficulty. Adsorption increases with the increases in pressure and decreases as temperature is increased.According to adsorption theory of catalysis, the speed of the reaction increases because

Number of hydrogen bond formed between adenine and thymine to connect each other is /are
