Quality of diesel fuel is expressed in terms of parameter called?

 Why is less caffeine actually isolated than is suggested by the calculation

3.(b) (i) Explain why o-nitrophenol has lower boiling points and lower water solubility as compared

with their m- and p- isomers.

(ii) Compare the acidity of ethanol and phenol by using dilute sodium hydroxide aqueous

solution. Explain why such acidity is observed

a) Give the structure of an alkene (or alkenes) with the same number of carbon atoms for the synthesis of the following alcohols:

(i) Butan-2-ol

(ii) 1-Methylcyclohexanol

(iii) tert-butylalcohol

(iv) 1-Methylcyclopentanol

(v) 2-Methylpropan-2-ol 

(b) Write the mechanism for the sulfuric acid catalyzed dehydration of alcohols in 2. (a) (ii) & (iii) and state the rule that determines the products of the reaction. 

Give a short explanation for each of the following observations:

(i) Alcohols with three or fewer carbon atoms are soluble in water. Those with four carbon atoms are sparingly soluble and those with five of more carbon atoms are insoluble in water

. (ii) Propanol (Mw = 60) has a higher boiling point than butane (Mw = 58).

(iii) The decreasing order of acidity of alcohol is 1° > 2° > 3°

(iv) 2-Chloroethanol is more acidic than ethanol. 

During a glucose tolerance test, the serum glucose concentration of a patient was found to be  131 mg/dL. Convert the concentration to grams per liter.

Mr. John starts his car from home at rest and accelerates uniformly at a rate of 2m/s² for 2s. He maintains a constant velocity for 10 seconds as he drives to a shopping mall. He then applies the brakes and then the car retards uniformly coming to rest in 5 seconds at the mall. Assuming that the journey is linear, for Mr. John’s car,

(a) draw the motion graph for the whole journey.

(b) find the maximum velocity.

(c) find the retardation in the last 5 seconds.

(d) determine the total distance traveled from home to the shopping mall.

(e) what was the average velocity?

Is water a solid or liquid
