Question

How to solve complicated internal compounds in aldol condensation process ,please give valid answer?​

Answer 1

Explanation:

An aldol condensation is a condensation reaction in organic chemistry in which an enol or an enolate ion reacts with a carbonyl compound to form a β-hydroxyaldehyde or β-hydroxyketone (an aldol reaction), followed by dehydration to give a conjugated enone.

Answer 2

Answer:

With direct cooling technology, the circulation of cool air in the refrigerator takes place naturally without any external aid. Hence, there is no way you can control the temperature distribution and it is bound to be uneven. Under such circumstances, you experience the collection of frost in and around the freezer box and this is why you have to press a button manually to defrost this ice. This is mostly the case in single door refrigerators.

Frost-free technology, on the other hand, allows for even distribution of cool air inside the fridge through the use of electric fans. Hence, there is no ice formation and your fridge stays frost-free! However, you must ensure that you opt for a reputed brand such as Hafele Appliances. Look for double door designs such as NR300NF as this model comes with amazing frost free technology.
