across a period, how does the electronegativity of a nonmetal affect the acidity of its binary hydride

1 answer:

3 0

1) Across the period as one moves from left to right, atomic size decreases.

2) Consider 3rd period elements containing non-metal i.e Si, P, S and Cl.

3) Here, atomic radius of these elements are in following order Si>P>S>Cl.

4) However, electronegative of these elements increases as we move from left to right

5) Thus, the corresponding hydrides have higher electro-negativity difference,as one moves from left to right.

6) Due to this, bond polarity increases from left to right,

7) Increase in bond polarity, results in increasing proton donating capability.

8) Therefore, acidity increases as one moves along the period.

Methanethiol, CH3SH, has a substantial dipole mement (1.52) even though carbon and sulfer have identical electronegativities. Ex

AleksAgata [21]

Answer:

The whole molecule is polar because Sulfur has lone pairs but Carbon doesn't. Lone pairs count more toward polarity, shifting dipole toward S.

Explanation:

Even though carbon and sulfur have identical values of electronegativities, the molecule, $CH_3SH$ is polar because of the presence of the lone pairs on the sulfur atom.

The C-S bond is not polar because the both the atoms have electronegatiivty. <u>But S has lone pairs which can attract the bond pairs of the bond between the S and H and thus acquires slightly negative charge and H acquires slightly positive charge.</u>

What do scientists believe formed the moon's craters and regolith

seraphim [82]

Answer:

What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

What type of heat transfer is a beaker on a hot plate an example of?

sesenic [268]

Heat transfer to a beaker on a hot plate is an example of conduction.

Explanation:

Conduction is a process where heat is transferred from one particle to another particle. Conduction is mainly possible in case of solids.In case of solids the atoms as well as the molecules are tightly packed through which the kinetic energy can easily pass. Conduction takes place when both the objects are touching each other. But in case of liquids molecules are loosely packed as a result convection takes place.
