In which structure are three atoms bonded together in a straight line?A poly(ethene), ] ( )CH 2 CH 2 nB propane, C 3H8C silicon tetrachloride, SiCl 4D sulfur hexafluoride, SF 6

To determine the structure in which three atoms are bonded together in a straight line, we need to analyze the given options: poly(ethene), propane, silicon tetrachloride, and sulfur hexafluoride.

A) Poly(ethene) is a polymer composed of repeating units of ethene monomers. It consists of a long chain of carbon atoms with two hydrogen atoms bonded to each carbon atom. Therefore, it does not have three atoms bonded together in a straight line.

B) Propane is a hydrocarbon with the chemical formula C3H8. It consists of three carbon atoms bonded together in a straight line, with eight hydrogen atoms attached to the carbon atoms. So, propane does have three atoms bonded together in a straight line.

C) Silicon tetrachloride has the chemical formula SiCl4. It consists of a silicon atom bonded to four chlorine atoms. Therefore, it does not have three atoms bonded together in a straight line.

D) Sulfur hexafluoride has the chemical formula SF6. It consists of a sulfur atom bonded to six fluorine atoms. Therefore, it does not have three atoms bonded together in a straight line.

Based on the analysis, the structure in which three atoms are bonded together in a straight line is option B, propane (C3H8).
