Who among the following is not a recipient of Nobel Prize in Chemistry in 2022 ?
- (a)Carolyn R. Bertozzi
- (b)Benjamin List
- (c)Morten Meldal
- (d)K. Barry Sharpless
Correct — B, Benjamin List. The 2022 Nobel Prize in Chemistry went to Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless 'for the development of click chemistry and bioorthogonal chemistry.' Benjamin List was NOT among them — he had won the Chemistry prize a year earlier, in 2021 (shared with David MacMillan) for asymmetric organocatalysis. So the person who is not a 2022 laureate is Benjamin List.
- (a)Carolyn R. Bertozzi — She IS a 2022 chemistry laureate, honoured for developing bioorthogonal chemistry — reactions that work inside living systems.
- (c)Morten Meldal — He IS a 2022 chemistry laureate, sharing the prize for click chemistry (developed independently of Sharpless).
- (d)K. Barry Sharpless — He IS a 2022 chemistry laureate — and this was his second Nobel in Chemistry (his first came in 2001).
The 2022 Nobel Prize in Chemistry recognised 'click chemistry' — a way of snapping molecular building blocks together quickly and reliably — and its extension into living cells, 'bioorthogonal chemistry.' The three laureates were Bertozzi, Meldal and Sharpless.
The question mixes in Benjamin List, a genuine but different-year laureate (2021), to catch students who remember the name but not the year. Anchor the three 2022 names to 'click chemistry' and remember Sharpless became a rare two-time chemistry Nobel winner.
- 2022 Chemistry Nobel: Carolyn R. Bertozzi, Morten Meldal and K. Barry Sharpless.
- The citation was for click chemistry and bioorthogonal chemistry.
- K. Barry Sharpless won his second Chemistry Nobel in 2022 (first in 2001).
- Benjamin List won the 2021 Chemistry Nobel (with David MacMillan) for asymmetric organocatalysis.
Benjamin List belongs to 2021, not 2022 — hence option (b).
- Recognising a name (Benjamin List) but attaching it to the wrong year.
- Forgetting Sharpless is a repeat winner and doubting his 2022 award.
Asked as an 'odd one out' item mixing the current year's laureates with a recent adjacent-year winner.
