Reagents that give effervescence when reacted with 1-pentyne:
There are several reagents from the given list that would give effervescence when reacted with 1-pentyne. Effervescence typically occurs when a gaseous product is formed during a chemical reaction. Let's analyze each reagent and determine if it would produce effervescence when reacted with 1-pentyne.
1. NaOH (l):
Sodium hydroxide (NaOH) is a strong base commonly used in various chemical reactions. When NaOH reacts with 1-pentyne, it would produce a salt and water, but no gaseous product. Therefore, NaOH would not give effervescence.
2. CH3CH2ONa (ll):
Sodium ethoxide (CH3CH2ONa) is an alkoxide compound. When reacted with 1-pentyne, it would also produce a salt and water, but no gaseous product. Therefore, CH3CH2ONa would not give effervescence.
3. CH3CH2MgBr (lll):
Ethylmagnesium bromide (CH3CH2MgBr) is a Grignard reagent commonly used in organic synthesis. When reacted with 1-pentyne, it would produce an alkene and magnesium bromide. Again, no gaseous product would be formed, so CH3CH2MgBr would not give effervescence.
4. NaH (IV):
Sodium hydride (NaH) is a strong base that can deprotonate various organic compounds. When reacted with 1-pentyne, it would abstract a proton and form sodium pentynide. This reaction would indeed produce a gaseous product (hydrogen gas), resulting in effervescence. Therefore, NaH would give effervescence.
5. NaNH2 (V):
Sodium amide (NaNH2) is a strong base commonly used in organic synthesis. When reacted with 1-pentyne, it would also abstract a proton and form sodium pentynide. Like NaH, this reaction would produce hydrogen gas, resulting in effervescence. Therefore, NaNH2 would give effervescence.
6. Na (VI):
Sodium metal (Na) is a strong reducing agent. When reacted with 1-pentyne, it would not produce any gaseous product. Therefore, Na would not give effervescence.
7. NaHCO3 (VII):
Sodium bicarbonate (NaHCO3), also known as baking soda, is commonly used as a leavening agent. When reacted with an acid, it produces carbon dioxide gas, which causes effervescence. However, 1-pentyne is not an acid, so NaHCO3 would not give effervescence in this case.
8. [(CH3)2CH]2NLi (VIII):
Diisopropylamine lithium salt ([(CH3)2CH]2NLi) is a strong base used in organic synthesis. When reacted with 1-penty
