Which element has highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.

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

The following features will have the effect of creating a higher boiling point:

1. the presence of a longer chain of atoms in the molecule (more polarizable)
2. functional groups that are more exposed (that is, at the end of a chain, rather than in the middle)

Which has the highest boiling point?

Carbon has the highest melting point at 3823 K (3550 C) and Rhenium has the highest boiling point at 5870 K (5594 C).

Why does boiling point increase across a period?

Melting and boiling points increase across the three metals because of the increasing strength of their metallic bonds. The number of electrons which each atom can contribute to the delocalized “sea of electrons” increases. … The “sea” is progressively nearer to the nuclei and thus is more strongly attracted.

Which order of boiling point is correct?

The decreasing order of boiling points (highest to lowest) are as follows: (III) > (I) > (II) alcohol > ether > alkane. “NF ”mar fil Therefore, it has the highest boiling point. Key Terms. Compound B does not form hydrogen bond.

Which has higher boiling point alcohol or aldehyde?

In alcohols hydrogen bonding exists and hence has a greater boiling point than aldehyde and ketone. … So the overall molecular mass for a single molecule increases and hence the boiling point increases.

Which gas has highest boiling point in air?

-So, the order of the gases in which they will get distilled out is: Neon >Krypton> nitrogen >oxygen.
…

Which group has lowest melting point?

The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon. The unity used for the melting point is Celsius (C).

Which element has low melting point and boiling point?

Helium has the lowest melting and boiling point among all elements.
