Real questions that test this
रेणूमध्ये अणू _________ बलाद्वारे एकत्रित ठेवले जातात.
1)रेण्वांतरीक / Intermolecular forces
2)अंत रेणु / Intramolecular forces✓ Correct
3)द्विअग्र / Dipole - Dipole forces
4)वान डर वॉल्झ / Van der Wall's forces
Atoms in a molecule are held together by chemical bonds formed through electron sharing or transfer.
खालीलपैकी कोणते लुईस आम्ल नाही ? Which of the following is not a Lewis acid?
1)बेरीअम क्लोराईड (BaCl₂)✓ Correct
2)बोरॉन ट्राय क्लोराईड (BCl₃)
3)बेरीलीअम क्लोराईड (BeCl₂)
4)बोरॉन ट्राय फ्लोराईड (BF₃)
A Lewis acid is an electron-pair acceptor. Barium chloride (BaCl2) is an ionic compound and acts as a source of chloride ions, not an electron-pair acceptor in the Lewis sense, unlike boron and beryllium halides which have incomplete octets.
