A water tank has steps inside it. A monkey is sittin on the topmost step (i.e.,the first step). The water level is at the ninth step. He jumps 3 steps down and then jumps back 2 setps up. In how many jumps will he reach the water level.

A water tank has steps inside it. A monkey is sittin on the topmost step (i.e.,the first step). The water level is at the ninth step. After drinking water, he wants to go back. For this, he jumps 4 steps up and then jumps back 2 steps down in every move. In how many jumps will he reach back the top step?

A water tank has steps inside it. A monkey is sittin on the topmost step (i.e.,the first step). The water level is at the ninth step. If the number of steps moved down is represented by negative integers and the numbe of step moved up by positive integers, represent his moves in par (i) and (ii) by completing the following: (a) -3+2... =-8 (b) 4-2+...=8. in (a) the sum (-8) represents going down by eight steps. So what will the sum 8 in (b) represent?

Di-tert-glycols rearrange in the presence of acid to give alpa -tertiary ketones. The trivial name of the simplest glycol of this type is pinacol, and this type of reaction therefore is named pinacol rearrangement (in this specific case, the reaction is called a pinacol-pinacolone rearrangement). The rearrangement involves 4 steps. one of the hydroxyl groups is protonated in the first step. A molecule of water is eliminated in the second step and a tertiary carbocation is formed. The carbocation rearranges in the third step into a more stable carboxonium ion via a [1,2] rearrangement. In the last step, the carboxonium ion is deprotonated and the product ketone is obtained. How many products obtained in above reaction?

A student has set up an apparatus to show that " CO_(2) is released during respiration". After about I hour he observes no change in the water level in the delivery tube. Write two possible reasons for the failure of the experiment.
