1, 3-Diaxial kev sib cuam tshuam yog kev sib cuam tshuam ntawm cov axial hloov pauv nyob rau ntawm carbon atom 1 ntawm lub nplhaib cyclohexane thiab hydrogen atoms (los yog lwm yam hloov pauv) nyob ntawm carbon atoms 3 thiab 5.
Diaxial kev sib cuam tshuam txhais li cas?
Diaxial kev sib cuam tshuam (1, 3-diaxial kev sib cuam tshuam): Ib qho kev cuam tshuam (feem ntau yog ua tsis taus pa) ntawm ob lub axial hloov ntawm lub nplhaib cyclohexane. … Lub bromine atom tsis muaj kev sib cuam tshuam diaxial hauv qhov kev sib haum xeeb, vim nws yog equatorial.
Vim li cas thiaj hu ua 1/3 Diaxial interactions?
Lub zog sib txawv ntawm ob qho kev sib txawv los ntawm kev sib txawv, hu ua 1, 3-diaxial kev sib cuam tshuam, tsim thaum pawg axial methyl ntsib kev sib tw steric nrog ob axial hydrogens nyob rau tib sab ntawm lub cyclohexane nplhaib.
Tus nqi zog ntawm 1/3 Diaxial cuam tshuam ntawm cov tshuaj chlorine thiab methyl yog dab tsi?
Yog li tus nqi hluav taws xob ntawm a1, 3 diaxial kev sib cuam tshuam ntawm cov tshuaj chlorine thiab ib pawg methyl yog 10, 96 kJ / mol.
flagpole kev sib cuam tshuam yog dab tsi?
Nyob hauv lub nkoj conformation ob daim ntawv cog lus liab (2) hu ua flagpole bonds. Cov hydrogen atoms ntawm flagpole bonds yog hu ua flagpole hydrogens. Qhov ze ze ntawm flagpole hydrogens ua rau steric strain. Eclipsing ntawm carbon-hydrogen bonds ntawm cov atoms uas nyob ib sab (3) ua rau torsional strain.
