Ammonia, NH3, reacts with incredibly strong bases to produce the amide ion, NH2-. Ammonia can also react with acids to produce the ammonium ion, NH4+. (a) Which species (amide ion, ammonia, or ammonium ion) has the largest H¬N¬H bond angle? (b) Which species has the smallest H¬N¬H bond angle?

Hi everyone here we have a question telling us that al canes contain only single bonds. Al Kane's contain double bonds and all kinds contain triple bonds. Consider the compounds methane, ethane and Athene, which would have the smallest carbon to carbon, to hydrogen bond angle and which would have the largest carbon to carbon to hydrogen bond angle. So let's start with ethane. Its structure will have three hydrogen bonded to a carbon single bonded to another carbon And three more hydrogen. It has four groups around carbon, making it tetra. He drel With a bond angle of 109.5°. Now let's look at a theme. It will have two hydrogen bonded to a carbon Double bonded to another carbon and two more hydrogen. It has three groups around carbon, which makes it Trigon a lot plainer And 120°. Lastly, let's look at it thin. It has a hydrogen single bonded to a carbon triple bonded to another carbon single bonded to a hydrogen. It has two groups around carbon, making it linear, With a bond angle of 180°. So our smallest is going to be Assane And our largest is going to be 18. And those are our answers. Thank you for watching. Bye!
