7

¿Qué tipo de reacción química sobre los alquinos produce aldehídos o cetonas?

8

¿Como se denomina este alquino según IUPAC?

Explicación

El punto de ebullición de los alquinos, aumenta con la longitud de la cadena. Mientras más átomos de carbono contenga, mayor su punto de ebullición. Esto se debe a que a medida que aumenta la longitud de la cadena, aumenta el número de enlaces intermoleculares con el agua, por ende, se necesita mayor temperatura para alcanzar el cambio de estado

Recuerda, los hidrocarburos son moléculas no polares mientras que el agua es una molécula polar, por ende, son difíciles los enlaces puente hidrógeno entre ambos. Por ello, son prácticamente insolubles en agua
