NAME-FOSU-MENSAH EMMANUEL ID NUMBER-10372921 VITAMINS Vitamins are organic compounds which are needed in small quantities to sustain life. We get vitamins from food‚ because the human body either does not produce enough of them or none at all. An organic compound contains carbon. When an organism cannot produce enough of an organic chemical compound that it needs in tiny amounts‚ and has to get it from food‚ it is called a vitamin.

the trans‚ trans-1‚4-diphenyl-1‚3-butadiene‚ which is formed by a Wittig reaction along with the cis‚ trans isomeric diene. The reaction is carried out in two steps. First the Wittig salt is obtained through a simple nucleophilic displacement of chloride ion by triphenylphosphine. When treated with base‚ the Wittig salt forms a ylide which is a carbanion that acts as a nucleophile and adds to the carbonyl group. In this experiment‚ cinnamaldehyde is used as the carbonyl compound and yields mainly the

Salt and the effect it has on water. Do you like salt? Do you put it on your food to make it taste better? Salt doesn’t just make food taste better; it can change the freezing and boiling point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis
