Answer:
butan-2-ol
Explanation:
The reaction is of an alkene with water in acidic medium. This will give addition product where water will add on the alkene according to Markovnikov's rule.
However, as alkene is symmetrical,w we will get single addition product.
The steps will be
a) There will be protonation of alkene with the acid (the catatlyst), resulting in formation of carbocation.
b) the carbocation formed will be attacked by water molecule, following by deprotonation to give alcohol.
The reaction is shown in the figure.

Answer:
6.32 × 10⁻³
3.2560008× 10⁷
5.630× 10⁰
9.5002× 10¹
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.00632
In scientific notation = 6.32 × 10⁻³
32,560,008
In scientific notation = 3.2560008× 10⁷
5.630
In scientific notation = 5.630× 10⁰
95.002
In scientific notation = 9.5002× 10¹
