Is an Unsaturated Hydrocarbon Converted to Saturated When Reacted with Hydrogen?

Click For Summary

Discussion Overview

The discussion revolves around the conversion of unsaturated hydrocarbons to saturated hydrocarbons when reacted with hydrogen. Participants explore the implications of this reaction in the context of a homework problem, focusing on the definitions and characteristics of hydrocarbons.

Discussion Character

  • Homework-related, Conceptual clarification

Main Points Raised

  • Some participants note that C=C double bonds indicate a hydrocarbon is unsaturated, distinguishing it from alkanes, which are saturated.
  • There is a question about whether the reference is to the starting hydrocarbon or the resulting hydrocarbon after the reaction with hydrogen.
  • Participants emphasize the importance of focusing on the product of the reaction and what can be inferred about it.
  • One participant suggests that if an unsaturated hydrocarbon reacts with hydrogen, it should yield a saturated hydrocarbon, proposing that this leads to a specific answer in the context of the homework problem.
  • Another participant agrees with the approach of considering the product of the reaction as a means to solve the problem.

Areas of Agreement / Disagreement

Participants generally agree on the definitions of saturated and unsaturated hydrocarbons, but there is some uncertainty regarding the specific focus on the starting versus resulting compounds in the context of the homework question.

Contextual Notes

There are unresolved aspects regarding the exact nature of the reaction and the definitions being applied, which may depend on the context of the homework problem.

Homework Equations

The Attempt at a Solution


C=C double bonds means that it is not an Alkane because an Alkane is saturated hydrocarbon. So the answer should be from A, B or C.

Which compound do you refer to - starting hydrocarbon, or the resulting hydrocarbon?

Then you are right, but in no way it moves you ahead. Concentrate on the product - what do you know about it? (Or: what do you expect it to be?)

When an unsaturated hydrocarbon reacts with hydrogen, does it forms a saturated hydrocarbon? If this is the case, the the answer should be C.

And that's the correct approach to the problem.
