Question

explain vanť hoff rule.......​

Answer 1

Explanation:

In organic chemistry, the Le Bel–Van 't Hoff rule states that the number of stereoisomers of an organic compound containing no internal planes of symmetry is 2n, where n represents the number of asymmetric carbon atoms. Joseph Achille Le Bel[1] and Jacobus Henricus van 't Hoff[2] both announced this hypothesis in 1874 and that this accounted for all molecular asymmetry known at the time.[3]

As an example, four of the carbon atoms of the aldohexose class of molecules are asymmetric, therefore the Le Bel–Van 't Hoff rule gives a calculation of 24 = 16 stereoisomers. This is indeed the case: these chemicals are two enantiomers each of eight different diastereomers: allose, altrose, glucose, mannose, gulose, idose, galactose, and talose

Answer 2

HLO MATE HERE IS UR ANSWER.

⭐. According to vanť Hoffś rule , with the increase in every 10degree C , the rate of metabolic activities of the animal doubles.

⭐. If stated in reverse, for every decrease of 10 degree C temperature the rate of metabolic reactions is halved

⭐. The temperature effect on the rate of reaction is expressed interms of temperature coefficent Q10.

⭐. Q10 is the ratio between the rate of reaction at Xdegree C and rate of reaction at ( X-10degreeC) .

⭐. In living organisms , the value ofQ10 is about2.0 That means , the rate of metabolism doubles for every 10 degree C increasing temperature.
