You are working in a laboratory, and you are given the task of converting cyclopentene into 1, 5-pentanediol. Your first thought
Helen [10]

Answer:

Reagent A = H_3O^+

Reagent B=  Na_2Cr_2O_7~H_2SO_4~H_2O

Intermediate C= δ-Valerolactone

Explanation:

In the reaction from the alkene to the alcohol, we can use the <u>alkene hydration</u> in which the hydronium ion is added to the double bond followed by the attack of water to produce the <u>alcohol</u>.

Then in the conversion from alcohol to ketone can be produced if an <u>oxidant reactive</u><u> </u>is used. In this case the <u>Jones reagent </u>( Na_2Cr_2O_7~H_2SO_4~H_2O).

The intermediate is a structure produced by a <u>peroxyacid</u>. This reaction would introduce an <u>ester group </u>in the cycle generating the δ-Valerolactone (Figure 1).

A student calculates the volume of a graduated cylinder to be 43.26 ml. The actual volume is 42.32 ml. What is the percent error
Tpy6a [65]

Answer:

2.2%

Explanation:

Percentage error,

You apply the formula,

[(Estimated value - Actual value)/Actual value] × 100%

; [(43.26 - 42.32)/42.32] × 100

; (0.94/42.32) × 100

; 0.022 × 100
