The correct Answer is:
To solve the question, we need to analyze the two statements provided: **Statement 1**: BCl₃ and CCl₄ do not undergo hydrolysis. **Statement 2**: Both B and carbon do not have empty d-orbitals. ### Step 1: Analyze Statement 1 - **BCl₃**: Boron has the electronic configuration of 1s² 2s² 2p¹. In bonding, one of the 2s electrons is promoted to a 2p orbital, allowing boron to form three sp² hybrid orbitals. This results in one empty p orbital. Because of this empty orbital, BCl₃ can accept a lone pair from water (H₂O), allowing it to undergo hydrolysis to form H₃BO₃ and HCl. - **CCl₄**: Carbon has the electronic configuration of 1s² 2s² 2p². When forming bonds, the 2s electron is promoted to a 2p orbital, resulting in four sp³ hybrid orbitals. Carbon does not have any empty orbitals available to accept a lone pair from water. Therefore, CCl₄ does not undergo hydrolysis. **Conclusion for Statement 1**: BCl₃ can undergo hydrolysis, while CCl₄ cannot. Thus, Statement 1 is **false**. ### Step 2: Analyze Statement 2 - Both boron and carbon have their outermost electrons in the second shell (n=2), which contains only s and p orbitals. There are no d-orbitals in the second shell. Therefore, it is accurate to say that both boron and carbon do not have empty d-orbitals. **Conclusion for Statement 2**: This statement is **true**. ### Final Conclusion - Statement 1 is false because BCl₃ can undergo hydrolysis while CCl₄ cannot. - Statement 2 is true because both boron and carbon do not have empty d-orbitals. Thus, the correct answer is that Statement 1 is false and Statement 2 is true. ### Summary of the Solution - **Statement 1**: False (BCl₃ can undergo hydrolysis; CCl₄ cannot) - **Statement 2**: True (Both boron and carbon do not have empty d-orbitals)
