Condensation reactions (also known as dehydration synthesis) are a very common type of organic reaction. describe what happens in a condensation reaction and give two different examples of condensation reactions. indicate what types of compounds are involved in each example.

Condensation reaction may be defined as the reaction in which two molecules are joined together by the release of small molecules like water, ammonia and ether. The water is removed during the condensation reaction, hence also known as dehydration reaction.

The step wise molecules are added in the condensation reaction to form the product and maintain the equilibrium of the reaction. For example : joining of ethylalochol and ethanoic acid leads to the formation of ester. The OH of carboxylic acid and H of alcohol are removed as water molecule in the reaction.

The addition of glycine and alanine to form the protein. The removal of H ammonia from glycine and OH from the carboxylic acid of alanine. These two molecules are linked together by peptide bond.

answer; i believe that the correct answer is (light);

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
