Unfortunately, an answer to this requires a quick dip into orbital theory. You may have heard of s, p and d orbitals; carbon as a main group element of group 14 has the electronic configuration of [He]2s22p2[He]2s22p2, meaning two of its electrons are in an s orbital and two in p orbitals in its atomic ground state. The process by which these orbitals form bonds is simply overlap: If you have two orbitals that can be moved together and these two orbitals overlap, you generate a bonding and an antibonding orbital from these two. (This is a mathematical operation known as linear combination; plugging two orbitals into a linear combination means that exactly two orbitals are mathematically required to come out of the linear combination.) The bonding (or antibonding) orbitals that are generated by this process are labelled σ or π orbitals. Note that these are the Greek letters corresponding to s and p: a σ orbital is basically an s orbital streched in one direction and a π orbital is a p orbital streched in the same manner. Due to a number of constraints that you will learn about soon enough™, a carbon–carbon triple bond C≡CC≡C will consist of one σ bond and two π bonds as shown in the image below. Carbon-carbon triple bond showing the orbitals employed Figure 1: H−C≡C−HH−C≡C−H showing the σ and π orbitals required to make the respective bonds. Image taken from jahschem.wikispaces.org. See how two of the three possible p orbitals on each carbon (figure 1’s left half) overlap

Ammonia has one nitrogen and three hydrogen and three hydrogen depend on nitrogen for covalent bond so dependency on nitrogen is more than hydrogen so it is central atom

When a compound is ionized in a solution it forms cations and anions . When we add a more ionic substance to the solution which have a common ion as in the previous compound then it affects the equilibrium and may reverse the process. This effect of a common ion is called common Ion effect.
