The name given to the group delimited in the image is ethyl.
<h3>What is ethyl?</h3>
It is a hydrocarbon from the alkyl functional group.
Ethyl is a substituent derived from ethane. The formula for ethane is , whereas, ethyl has one H less than ethane.
Thus, the formula for ethyl is .
Looking at the delimited portion of the image, 2 C atoms in C-C bond are bonded by 5 H atoms.

<u>Answer:</u> The number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
<u>Explanation:</u>
Huckel's rule is used to determine the aromaticity in a compound. The number of delocalized electrons are calculated by using the equation:
where,
n = 0 or any whole number
- Calculating the value of electrons for n = 0
Putting values in above equation, we get:
- Calculating the value of electrons for n = 1
Putting values in above equation, we get:
- Calculating the value of electrons for n = 2
Putting values in above equation, we get:
Hence, the number of electrons for n = 0, 1 and 2 are 2, 6 and 10 respectively.
Answer: The correct answer is Aldose.
-
A disaccharide is produced when two monosaccharides are linked by a glycosidic bond.
- Any carbohydrate which has six carbon atoms is called as hexose. It is a monosaccharide. The functional group in hexose can be aldehyde or ketone.
- Ketose is a carbohydrate which contains ketone as a functional group.
Aldose, as the name suggests, it means having aldehyde group. Thus, it is a carbohydrate which has aldehyde as a functional group.
Example- D- Glyceraldehyde.
Answer:
0.1159 M
Explanation:
Using the formula below:
CaVa = CbVb
Where;
Ca = concentration/molarity of acid (M)
Cb = concentration/molarity of base (M)
Va = Volume of acid (mL)
Vb = volume of base (mL)
According to this question, the following information were given:
Ca = ?
Cb = 0.2831 M
Va = 26.86 mL
Vb = 11.00 mL
Using CaVa = CbVb
Ca × 26.86 = 0.2831 × 11
26.86Ca = 3.1141
Ca = 3.1141 ÷ 26.86
Ca = 0.1159
The molarity of the acid (H2SO4) solution is 0.1159 M
<h3><u>Answer;</u></h3>
<em> D) It can be mass produced.</em>
<h3><u>Explanation;</u></h3>
- <em><u>Synthetic materials</u></em> are those materials that are <em><u>man-made, that is they are synthesized in the lab or in industries.</u></em> They include synthetic fibers such as nylon, polyester and acrylic among others.
- <em><u>Synthetic materials</u></em> have a range of advantages over natural materials. For example, synthetic materials are durable than natural ones, they are cheap, they do not shrink and also resistant to chemicals among others.
- Additionally, synt<em><u>hetic materials such as synthetic fibers they can be mass produced in industries or in the labs. </u></em>
