The molecular structure of the organic lubricants consists of ________

1.	The molecular structure of the organic lubricants consists of ____________(a) pyramidal(b) tetrahedral(c) trigonal planar(d) long chainI had been asked this question in an interview for job.I'd like to ask this question from Classification of Lubricants topic in division Lubricants of Applied Chemistry
Answer» Right answer is (d) long chain Explanation: The molecular structure of the organic LUBRICANTS is in the form of long chains. The molecular chains are PARALLEL. The bonding strength between the molecules is very weak and MAY slide on each other.
