1-Chloro butane on reaction with alc KOH gives?

The reaction of 1-chlorobutane with alcoholic KOH typically results in the substitution of the chloride group with the alkoxide ion from KOH, producing butanol and potassium chloride. This reaction is known as an SN2 reaction, where the nucleophile (OH- from KOH) attacks the electrophilic carbon bound to the leaving group (Cl) in a one-step mechanism.


At STP an element that is brittle solid and a poor conductor of heat electricity could have atomic no of A. 12 MgB. 13 AlC. 16 SD. 17 ClJust tell me how to figure this out.?

To figure this out, we need to identify the element that fits the given characteristics. Brittle solid and a poor conductor of heat and electricity are properties of nonmetals. Among the options provided, element D with an atomic number of 17 (Cl) is a nonmetal at STP.


Distinguish between chloroform and carbon tetracholride?

Chloroform is a colorless liquid with a sweet smell, while carbon tetrachloride is a colorless liquid with a strong odor. Chloroform is used in medical and industrial applications, while carbon tetrachloride was once used as a solvent but is now considered toxic and harmful to health.


How much 80 percent alcohol added solution must be added to 7 liters of 60 percent alcohol to make sure a mixture of 73 percent?

80x + 60*7 = 73*(x+7) so x = 91/7 = 13 L (of 80% alc)Added noteto deal with the so called 'dilution contraction' of total volumeIf it were % by MASS ( %m/m), it's quite easy to do (based on the 'Mass Conservation Law). You calculate with mass (kg) and mass-% (%m/m) i.s.o. volume (L) and vol% (%v/v).However if the meaning was: % by Volume ( %v/v) then calculation appears to become quite complicated, but not impossible if you know at least the density values of all solutions (original 80%v/v or 60%v/v and final 73%v/v).DO NOT use: (orig. volume) + (added volume) = final volume, as done above, if exact figures are necessary.It's only a rule of thump, an approximation. This is because fluids can contract on mixing at dilution. There is no rule such as: conservation of volume.Your case: 13 L + 7 L (is not equal but) < 20 L final solution.


How do you convert ethene to bromo ethane?

Cyclohexane can be converted into benzene by catalytic dehydrogenation in the presence of oxides of D block for ex V2O5, Cr2O3 etc. Cyclohexane when heated at 6000C in presence of Al2O3-Cr2O3 gives benzene.
