Is Br2 bigger than i2?

Is Br2 bigger than i2?

I2 has a higher boiling point than Br2. The atomic weights of Br and I are 80 and 127 respectively. Since I2 has higher molecular weight, it has stronger London dispersion forces so it has a higher boiling point than Br2.

Why does I2 have such a high boiling point?

Iodine is a larger molecule, with more electrons, than chlorine. Therefore Iodine has stronger intermolecular forces than chlorine, which require more energy to break. This results in Iodine having a higher boiling point than chlorine.

Which is more polarizable Cl2 or I2?

I2 is more polarizable than Cl2. I2 has a larger dipole than Cl2.

Which has higher boiling point I2 or Cl2?

The bigger the atoms, the more polarisable their electron clouds and the greater the dispersion forces. Hence boiling points are in order: I2 > Br2 > Cl2 > F2.

How do you know which compound has the highest boiling point?

First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. It is very important to apply this rule only to like compounds.

Which compound of C4H10 has a higher boiling point?

/2 In terms of electrons Cl2 and C4H10 should have similar boiling points, but the larger size of C4H10 accounts for its higher boiling point. 14.

What has the weakest surface tension?

Hexane

Which is stronger CH4 or C2H6?

Explain your answer. a.CHOCHor CHCHOH- Ethanol has more hydrogen bonds than CH3OCH3b.CHor CH– C2H6 has stronger intermolecular forces than CH4c.CHor SiH- SiH4 has more electrons than CH4 3.

Which molecule has the strongest intermolecular forces?

hydrogen bonding

Can ethanol hydrogen bond with itself?

Hydrogen bonding can occur between ethanol molecules, although not as effectively as in water. The hydrogen bonding is limited by the fact that there is only one hydrogen in each ethanol molecule with sufficient δ+ charge. The hydrogen bonding in the ethanol has lifted its boiling point about 100°C.

Can acetic acid hydrogen bond with itself?

As you know, water is a polar molecule that can form hydrogen bonds because of its partial negative oxygen atom and its partial positive hydrogen atoms. This means that the acetic acid molecules are free to form hydrogen bonds between themselves, i.e acetic acid forms dimers in benzene.

What bonds are in acetic acid?

In acetic acid, there are seven bonds between atoms. Even though the carbonyl carbon has a double bond, there is still a -bond between the carbon and oxygen. As a result, there are seven total -bonds in a molecule of acetic acid.

What type of bonds are in acetic acid?

Structure. In solid acetic acid, the molecules form chains, individual molecules being interconnected by hydrogen bonds. In the vapour at 120 °C (248 °F), dimers can be detected.
