The mass spectrum of an organic compound shows the relative abundances of M to be 34.76% and M 1 to be 2.632%. Assuming the peak

s are caused by C12 and C13 isotopes, determine the number of carbon atoms in the compound. The natural abundance of C12 is 98.93%, and the natural abundance of C13 is 1.07%.

The number of carbon atoms present in any compound is equal to seven.

<h3>How do we calculate the number of carbon atoms?</h3>

Number of carbon atoms present in any compound will be calculated by using the following equation:

No. of Carbon atoms = Relative intensity of M+1 peak / Natural abundance of C13

Intensity of molecular peak = 34.76%

Intensity of M+1 peak = 2.632%

Relative intensity of M+1 peak = (100/34.76)×2.632 = 7.57%

Given that natural abundance of M+1 = 1.07%

On putting values on above equation, we get

No. of C atoms = 7.57 / 1.07 = 7.07 = 7 (approx)

Hence number of carbon atoms is 7.

Fill in the blanks with appropriate options given in below:
jarptica [38.1K]

Answer:

1) -COOH

2) -NH2

3) hydrogen bonds

4) dispersion forces

5) -CH3

6) hydrogen bonds

7) negative

8) negative

9) positive

Explanation:

Alanine has a <u>-COOH</u> and a <u>-NH2</u> group available to form <u>hydrogen bonds</u> with water molecules.

Although there are some potential <u>dispersion forces</u> between the terminal <u>-CH3</u> group of alanine and hexane molecules, we expect the <u>hydrogen bonds</u> between alanine and water to be stronger.

Stronger intermolecular attractive forces between alanine and water lead to a more <u>negative ΔHmix</u> and more <u>negative (smaller positive)</u> ΔHsoln for water than for hexane.

The laws of superposition and original horizontality are best applied to _____.
vodka [1.7K]
The laws of superposition and original horizontality are best applied to sedimentary rocks.


Sedimentary rocks are types of rocks that are formed through deposition and subsequent cementation of such material at the Earth's surface and within bodies of water. The law of superposition and original horizontality applies because technically the layers of sediments from which sedimentary rocks are formed were originally deposited horizontally under the gravitational action.  Furthermore,  since sedimentary rock formation has an undisturbed sequence, then the basic law of geochronolgy (law of superposition) applies since oldest layer is at the bottom while the youngest layer is on top.
