Given below are two statements. In the light of the above statements, choose the correct answer from the options given below.
Statement I:Biodiesel can be created from vegetable oils and animal fats.
Statement II:Biodiesel viscosity is significantly lower than that of petroleum diesel.
ABoth Statement I and Statement II are correct
BBoth Statement I and Statement II are incorrect
CStatement I is correct but Statement II is incorrect ✓ Correct
DStatement I is incorrect but Statement II is correct
Correct answer: (C) Statement I is correct but Statement II is incorrect
Explanation
Statement 1 is correct but Statement 2 is incorrect about biodiesel.
Statement 1 holds, as biodiesel is made from vegetable oils and animal fats.
Statement 2 fails, since biodiesel viscosity is higher, not lower, than petroleum diesel.
Higher viscosity can hinder fuel flow and atomisation in engines.
Transesterification is used to reduce the viscosity of the raw oils.
Biodiesel is renewable, biodegradable and burns more cleanly.
