Answer:
120 V usually but its not given in the option so 110 V
Answer:
The answer to your question is: 190°C
Explanation:
Data
P1 = 535 torr
T1 = 19°C
P2 = 5350 torr
T2 = ?
Formula
T2 = 190°C
Answer:
3-methylenehexane
Explanation:
In this case, we have <u>two clues</u>.
<u>1) The hydrogenation reaction</u>
<u>2) The ozonolysis reaction</u>
See figure 1.
With this in mind, lets analyze each clue. In the first reaction, we know that only 1 molecule of is added to the unknown molecule. This indicates that we only have <u>1 double bond</u> in the molecule. Now, the next question is <u>where is placed the double bond?</u>
To answer this question, we have to use the second clue. In the ozonolysis reaction, a double bond is broken and is replaced with a carbonyl group. If, <u>formaldehyde</u> is formed the double bond is formed with a <u>primary carbon</u>. The primary carbons in the structure (given in the first reaction: 3-methylhexane) are carbons 1, 6, and 7. So, the double bond can be placed between carbons:
a) 6 and 5
b) 7 and 3
c) 1 and 2
To decide which one is the position of the double bond we have to keep in mind the <u>second product</u> of the ozonolysis reaction a <u>ketone</u>. With this in mind, the carbon bonded to the <u>primary one</u> (deduced by the formaldehyde) it has to be a <u>tertiary carbon</u>. The only option that has a primary carbon bonded to tertiary carbon is <u>b)</u>. (See figure 2)
Finally, with this in mind the structure is <u>3-methylenehexane</u>. To be sure, we can <u>check the formula</u> for the compound, and the <u>reactions</u>. (See figure 3)
I hope it helps!
