A reduction reaction can be carried on many organic compounds. It is the reverse of an oxidation reaction. Which of the following statements is true? A reduction reaction can be carried on many organic compounds. It is the reverse of an oxidation reaction. Which of the following statements is true? Reduction reactions are characterized by the increase in the number of carbon-oxygen bonds. Reduction reactions are characterized by the decrease in the number of carbon-oxygen bonds. Alcohols are reduced to aldehydes. Reduction reactions are characterized by the decrease in the number of hydrogen atoms.

Statement: Reduction reactions are characterized by the increase in the number of carbon-oxygen bonds……………….False.

The above statement is certainly not true. There will be change in the number of carbon-oxygen bonds before and after reduction. Examples include reduction of carbonyl group of aldehydes to alcohols which leads to change in the number of carbon-oxygen bonds from 2 to 1 as shown below.

Statement: Reduction reactions are characterized by the decrease in the number of carbon-oxygen bonds. …………….True.

Yes the above statement is correct. In some cases even the number of oxygens on the compound are reduced. For example in reduction of acids to alcohols by borane the number of carbon-oxygen bonds and number of oxygens are reduced.

Statement: Alcohols are reduced to aldehydes…………….. False.

Alcohols are reduced to the corresponding aliphatic compounds not to the higher oxidation state carbonyl compounds such as aldehydes..

Statement: Reduction reactions are characterized by the decrease in the number of hydrogen atoms…………….. False.

As shown below reduction reactions are characterized by the increase in the number of hydrogen atoms.

Example: Reduction of 2-butene to n-butane. In this example number of hydrogen atoms have increased by two.

Some uncharged organic compounds have so many polar functional groups that they are somewhat soluble in water. During an extraction such compounds reside partially in the water layer and partially in the water-immiscible organic layer. Why does the addition of a salt (like NaCl) to the aqueous phase often diminish the solubility of the polar organic (uncharged) compounds in the aqueous phase (the process is referred to as “salting out”)? Please explain.

CaCO3 can be roasted to produce CaO and CO2. This reaction is carried out in a flask connected to an open-end mercury manometer when the atmospheric pressure is 764 torr. If the pressure of the CO2 produced is 0.245 atm, determine the total pressure in the flask AND the height difference between the two arms of the manometer. I cant find the diference in height.
