Bent or linear?

Would a molecule with a double/triple bond on one side of a central atom and a single bond on the other side of that atom be linear or bent?

I believe the shape would depend on where the lone pairs of electrons are placed and not be affected by single or double bonds

I think it would be linear if there are no lone pairs on the central atom

If the central atom does not have lone pairs then it would be linear. Since there is a lack of lone pairs the other elements would not be pushed down. However, if there was a lone pair on the central atom, it would repel the other two elements. In this case they, would be pushed down and bent. Another way to call this is angular.

The shape depends on the number of lone pairs as well as their placement on the molecule.

Yeah, I agree, if the central atom does not have any lone pairs, then it would be linear.

Adding on, it would be linear because single and multiple bonds are treated as the same in the VSEPR model.

An example of a linear shape with a triple bond on one side and a single bond on the other side is hydrogen cyanide (HCN). A triple bond connects C to N and a single bond connects H to C. It has no lone pairs and 2 VSEPR regions, so the molecular shape is linear.

If there are no lone pairs then it would be linear because it is lacking the electron repulsion from the lone pairs.

geometry doesnt depend on whether bonds are double/triple but on the electron domains so if there are no lone pairs on the central atom it is linear

It would be linear if there are no lone pairs of electrons on the central atom. This is because the lone pairs are responsible for any repulsion between themselves and the bonded electrons. The bent shape/structure of any molecule can be attributed to this repulsion phenomenon. A linear shape would make the bonded electrons and lone electrons closer to each other whereas the bent shape distances them apart and can lessen the repulsion.

If there are no lone pairs on the central atom, then the shape of the molecule will be linear. However, if there are lone pairs on the central atom, the electron repulsion that they will create with the other bonds connecting the central atom will cause the shape to be bent.
