The answer is the upper right Fluorine is the most electronegative. 
alekssr [168]3 years ago
3 0

Answer: Option (a) is the correct answer.

Explanation:

It is known that when we move across a period from left to right in a periodic table then there will be decrease in size of elements. This is because of addition of electrons into the same sub-shell.

Whereas when we move down a group then there occurs an increase in size of atoms due to addition of new sub-shells.

As electronegativity is the ability of an atom to attract an electron towards itself. Hence, smaller is the size of an atom more will be the ability of its nucleus to attract a proton towards itself. As a result, higher will be its electronegativity.

For example, fluorine is the most electronegative element present in the periodic table.

Thus, we can conclude that upper right area of the periodic table has the highest electronegativities.

Name the functional group in the<br> following molecule:
Anna71 [15]

Answer:

B. Aromatic

Explanation:

Functional groups are groups that differentiate a specific organic compound from others. A functional group determines the chemical property of the compound that possesses it.

For example, just like alkene and alcohol functional groups have characteristics double bond (=) and hydroxyl (OH) group respectively, the image in the attachment of this question has a BENZENE RING at the core of its structure, hence, the organic compound can be regarded to have an AROMATIC FUNCTIONAL GROUP.

A stock solution of HNO3 is prepared and found to contain 13.5 M of HNO3. If 25.0 mL of the stock solution is diluted to a final
salantis [7]

Answer : The correct option is, (C) 0.675 M

Explanation :

Using neutralization law,

M_1V_1=M_2V_2

where,

M_1 = concentration of HNO_3 = 13.5 M

M_2 = concentration of diluted solution = ?

V_1 = volume of HNO_3 = 25.0 ml  = 0.0250 L

conversion used : (1 L = 1000 mL)

V_2 = volume of diluted solution = 0.500 L

Now put all the given values in the above law, we get the concentration of the diluted solution.

13.5M\times 0.0250L=M_2\times 0.500L

M_2=0.675M

Therefore, the concentration of the diluted solution is 0.675 M
