On a caterpillar's map, all distances are marked in millimeters. The caterpillar's map shows that the distance between two milkw
pychu [463]

Answer:

0.004012km

Explanation:

Problem:

Conversion of millimeters(mm) to Kilometers:

value given = 4012mm

Here, we are converting from a submultiple unit to a multiple unit.

Millimeter depicts 10⁻³m and kilometer stands for 10³m

Now, we must find how many exponents will take us from 10⁻³ to  10³

careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:

   i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³

Therefore,

       10⁶mm = 1km

      4,012mm = \frac{4012}{1000000} = 0.004012km

Which of the following would result in butyl phenyl ether as the major product? a. Reaction of phenoxide with 1-bromobutane b. R
AlladinOne [14]

Answer:

Reaction of 1-butanol with bromobenzene

Explanation:

The reaction would yield ether as the major product is the reaction of the 1-butanol with bromobenzene. This is because the reaction does not have the large percentage of the undesired side product. In fact, the major product is about 85 % in composition, compared to the 15 % of the minor product. Hence, the reaction is efficient.
