the hydrocyanic compund(HCN) i forget why. the Nitrogen is triple bonded that might have something to do with it.

You can work out the answer to this question yourself by applying the VSEPR theory. The things you must know are
1) Electron pairs of an atom repel each other. You must place them such that they are as much far away as possible.
2) Multiple bonds (double, triple) should be considered as a single pair of electrons
3) LP-LP > BP-LP > BP-BP is the decreasing order of repulsion between electron pairs. You must arrange the pairs such that there is minimum possible repulsion between the pairs.
Applying these, you'll find that HCN is the only linear molecule. (Draw the electron pairs to find out how!).

In order to answer this, you would have to draw the Electron Dot Structure of each. In doing so, you will see HCN would be linear.

BF3, just guessing
