UV Absorption Spectrum of 1, 3-Butadiene in n-Hexane
1. Introduction
UV absorption spectrum is a useful tool to identify the functional groups present in a compound. 1, 3-Butadiene is a conjugated diene, which shows characteristic UV absorption in the range of 200-300 nm.
2. Explanation of Options
a) max217nm (max = 21,000)
This option suggests that 1, 3-butadiene shows maximum absorption at 217 nm with a molar absorptivity of 21,000. This is the correct answer as conjugated dienes have a strong absorption at around 217 nm.
b) max214nm (max = 210)
This option suggests that 1, 3-butadiene shows maximum absorption at 214 nm with a molar absorptivity of 210. This is not the correct answer as the maximum absorption of conjugated dienes is around 217 nm.
c) max253nm (max = 50,000)
This option suggests that 1, 3-butadiene shows maximum absorption at 253 nm with a molar absorptivity of 50,000. This is not the correct answer as the maximum absorption of conjugated dienes is around 217 nm.
d) max250nm (max = 500)
This option suggests that 1, 3-butadiene shows maximum absorption at 250 nm with a molar absorptivity of 500. This is not the correct answer as the maximum absorption of conjugated dienes is around 217 nm.
3. Conclusion
Therefore, the correct answer is option 'A', which suggests that 1, 3-butadiene shows maximum absorption at 217 nm with a molar absorptivity of 21,000.

This option suggests that 1, 3-butadiene shows maximum absorption at 214 nm with a molar absorptivity of 210. This is not the correct answer as the maximum absorption of conjugated dienes is around 217 nm.
c) max253nm (max = 50,000)
This option suggests that 1, 3-butadiene shows maximum absorption at 253 nm with a molar absorptivity of 50,000. This is not the correct answer as the maximum absorption of conjugated dienes is around 217 nm.
d) max250nm (max = 500)
