In a private blockchain network, if there are three nodes - A, B, and C
A is connected to B
B is connected to C
But, why is A not connected to C?
Wouldn't that make the connections and ultimately the network more reliable?

I think if it so every peer will be connected to all the other peers. in this case we will have a DDOS risk and more bandwidth consumption.– Badr Bellaj ♦Sep 21, 2016 at 11:07

If all N nodes connected to all N-1 others, that would require a lot of bandwidth and work managing all these connections. There is a whole field of research dedicated to optimal connections distribution given a desired "network diameter".
Not to forget that certain network topologies, think NAT and port-forwarding, do not allow all nodes to connect to each other.
