Two constitutional isomers having molecular formula c4h6o are both symmetrical in structure. in their infrared spectra, neither isomer when in dilute solution has absorption in the 3600 cm−1 region. isomer a has absorption bands at approximately 3080, 1620, and 700 cm−1 . isomer b has bands in the 2900 cm−1 region and at 1780 cm−1 . propose a structure for a and two possible structures for b.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

im not exactly sure but i think its b!

let that person have a turn to speak : )

your answer would be “dry”
