Step 1: Criteria for Reactive Metal:
The most reactive metal is the one that loses electrons most easily. This corresponds to the lowest First Ionization Enthalpy (\( \Delta_i H_1 \)).
Step 2: Analyze Data:
- Element I: \( \Delta_i H_1 = 520 \) (Alkali metal, huge jump to \( \Delta_i H_2 \)).
- Element II: \( \Delta_i H_1 = 490 \) (Alkali metal, lower than I).
- Element III: \( \Delta_i H_1 = 1681 \) (Non-metal/Halogen).
- Element IV: \( \Delta_i H_1 = 2372 \) (Noble gas).
Comparing I and II, Element II has the lower ionization energy (490 < 520), making it the most reactive metal. Quick Tip: For metals, Reactivity \( \propto \frac{1}{Ionization Energy} \).

View Solution
Step 1: Formation of A (Grignard Reaction):
Reactant: Propanone (Acetone) \( CH_3COCH_3 \).
Reagent: \( CH_3MgBr \) followed by hydrolysis.
The methyl group attacks the carbonyl carbon.
Product A is tert-Butyl alcohol (2-Methylpropan-2-ol).
Structure of A: \( (CH_3)_3C-OH \).
Step 2: Formation of B (Dehydration):
Reagent: 20% \( H_3PO_4 \), 358 K. This causes dehydration of alcohol A.
Tert-butyl alcohol loses water to form an alkene.
Structure of B: 2-Methylpropene (Isobutylene). \( (CH_3)_2C=CH_2 \).
Step 3: Formation of C and D (Ozonolysis):
Reagent: \( O_3 \) followed by \( Zn/H_2O \) (Reductive Ozonolysis).
Break the double bond in B and add oxygen to each carbon. \( (CH_3)_2C=CH_2 \xrightarrow{O_3, Zn} (CH_3)_2C=O + O=CH_2 \).
Products:
1. Propanone (Acetone) \( (CH_3)_2CO \).
2. Methanal (Formaldehyde) \( HCHO \).
Step 4: Check Options:
The products are Propanone and Methanal.
Let's review the options provided in the image text (transliterated):
1. Ethanoic acid, ethanal
2. Ethanol, Propanone
3. Ethanal, Propanone
4. Propanal, Propanone
There seems to be a discrepancy. My derivation yields Propanone and Methanal.
Let me re-read the reaction scheme image carefully.
Reaction:
Reactant: Looks like Ethanoic acid? No, it's a carbonyl. \( CH_3-C(=O)-O-something \)? No.
Let's look at the first structure. It looks like an ester or anhydride?
Ah, looking closer at the crop (Question 158), the reactant is: \( CH_3-C(=O)-O-something \) or maybe an ester.
Wait, if it is an ester, Grignard reacts twice to give tertiary alcohol.
If the reactant is Ethyl Ethanoate (\( CH_3COOC_2H_5 \)):
1. \( 2 CH_3MgBr \) gives tert-butyl alcohol (A).
2. Dehydration gives isobutylene (B).
3. Ozonolysis gives Acetone + Formaldehyde.
Still Methanal.
Let's look at the reactant in the image again. It is \( O=C(CH_3)-... \). The bond points to... nothing?
Actually, it looks like a ketone structure \( R-C(=O)-R' \). If it's Acetone, the result is Acetone + Methanal.
Let's check if B could be different.
If the reactant was 2-butanone?
Grignard (Me) \(\to\) 2-methyl-2-butanol.
Dehydration \(\to\) 2-methyl-2-butene (Saytzeff).
Ozonolysis \(\to\) Acetone + Acetaldehyde (Ethanal).
This matches Option (C): Ethanal, Propanone.
So, the starting material must be Butanone (Ethyl methyl ketone) or equivalent that leads to 2-methyl-2-butene.
Re-examining the image: The reactant looks like \( CH_3-C(=O)-CH_2-CH_3 \) (Ethyl methyl ketone).
Let's verify this path:
1. Butanone + \( CH_3MgBr \) \(\to\) 2-Methylbutan-2-ol (A).
2. Dehydration \(\to\) 2-Methylbut-2-ene (B, Major product acc. to Saytzeff rule). Structure: \( CH_3-C(CH_3)=CH-CH_3 \).
3. Ozonolysis of B: Break double bond.
Left part: \( CH_3-C(CH_3)=O \) \(\to\) Propanone.
Right part: \( O=CH-CH_3 \) \(\to\) Ethanal.
This perfectly matches Option (C). Quick Tip: For Ozonolysis: simply erase the double bond and put an oxygen atom on each carbon. Dehydration of alcohols follows Saytzeff's rule: The more substituted alkene is the major product.
