meriva

<u>Answer:</u> The isomers are shown in the image below.

<u>Explanation:</u>

Isomers are defined as the chemical compounds having the same number and kinds of atoms but arrangement are different.

For the alkane having four carbon atoms and 1 bromine atom, the IUPAC name of the haloalkane is bromobutane

There are 4 possible isomers for the given haloalkane compound:

  1. 1-bromobutane
  2. 2-bromobutane
  3. 1-bromo-2-methylpropane
  4. 2-bromo-2-methylpropane

The isomers of the given organic compound is shown in the image below.

HELP ASAP!!!
Paraphin [41]
Solution..
---------------

Let's calculate the mass of CO₂.

We have (12+(16*2))
= 12+32
=44gmol¯¹..

a. What is the percent by mass of carbon?

Mass of carbon /mass of CO₂ × 100%

12/44 × 100%

=27.3%...

b. What is the percent by mass of oxygen?

Mass of oxygen/mass of CO₂ × 100%

(2×16)/44 × 100%

32/44 × 100%

=72.7%....

To check.. You'll add this two percentage compositions together and see of it gives 100%... If it does then we're good...

27.3%+72.7% = 100%.... Checked..

Hope this helped....?
